I noticed a Macheist bundle in my inbox three hours before the deal expired, and that Path Finder was in the list of apps. Since I’ve often toyed with switching to Path Finder I gave it a quick look (since the bundle cost was far cheaper than Path Finder alone). The first thing that attracted my attention was AirServer. This is an app that bridges a gaping hole in Apple’s hub — using your Mac as an AirPlay target. E.g. it makes using a $600 Mac Mini as a “media hub” significantly more painful than a $99 AppleTV puck. While this is obviously functionality Mac OS X should have out of the box, for $15 it fills a real need — and it works beautifully.
Clarify is another interesting program. The basic idea is to replace screensharing with illustrated tutorials by providing an integrated tool for writing, capturing screenshots, and annotating images (including blurring out stuff you don’t want to share). It’s a well-intentioned product, and it definitely has the right collection of features, but the UI is a little clumsy (e.g. despite providing a global menu, it offers no keyboard shortcut for snapping screenshots, doesn’t provide a “capture window” mode as far as I can tell; it’s easy to accidentally add text balloons to images by accident) and annoyingly inflexible (e.g. there’s no way I can find of adding two images side-by-side — before and after, say — to a single instruction, or of having multiple steps under one heading).
If I were creating such a program I’d try to combine screen-sharing with the functionality they’re providing — in other words, allow the user to video capture the whole process, then facilitate the snapping and markup of still images. As it is, I think (despite the best intentions) creating a tutorial with Clarify is more work than using — say — Screenflow. (And if video compression time is an issue, IShowU has that issue solved.)
I used to use Comic Life for creating short tutorials, but this involved using some other tool (I use command-shift-4 usually) for screen capture; on the whole I’d say Comic Life is still superior to Clarify despite not being intended for this task. Unfortunately, this applies to the old Comic Life — the current version is, I think, too narrowly focused on its intended purpose.
Fantastical is a well-regard (I believe) replacement for the app formerly known as iCal, and now widely (and correctly) ridiculed for its stupidly skeumorphic UI. Call me cynical, but I can only assume that it was bundled because there’s a new version on the way. The method for quickly generating appointments is beautiful (almost as good as the Newton). My main issue with it so far is that it doesn’t seem to replace Calendar completely.
For the uninitiated, Path Finder is an attempt to create a better Finder with tabbed browser windows, better command-line integration, and then add some kind of insane kitchen-sink list of features.
My original complaints about Path Finder have, in part, been addressed. I loved its column views (but I don’t use column views much) and I loved its tabbed windows (for which we continue to wait in vain for Apple to provide). Unfortunately, I listed some major annoyances issues with Path Finder 4 (it’s up to 6).
It also provides a whole bunch of hopelessly disorganized and marginally useful clutter.
It provides multiple redundant views of everything.
It can replace Finder (kind of) but the developers don’t really believe it so it does dumb things like reveal selected items in Finder windows rather than its own Windows.
The first problem has gotten, if anything worse, at least by default. To give but one egregious example — by default you can deploy up to three different “drawers” (you may not know or remember what a “drawer” in Mac OS X is, since it’s a UI dead-end Apple itself has pretty much abandoned). But you can turn off a whole bunch of its clutter.
In terms of functional clutter, by default, Path Finder uses its own replacements for TextEdit, Preview, and Terminal. I’m sure there are various ways in which the developers think they can improve on Apple’s apps, but it simply makes me shudder. Their Terminal and Preview replacements just annoy me. That said, there’s a damn good reason why they exist — which I’ll get to.
My final gripe (I’ll get back to the middle point) has been dealt with. Pathfinder now offers fine-grained options for inter-operating with Finder. By default, it simply supplements Finder, and lets Finder continue to do its thing. You can also configure it to kill Finder when it launches and relaunch it on exit. It can hide Finder’s desktop, and it can take Finder’s place for “reveal in Finder” functionality.
But the second issue — multiple redundant views of everything — is either something I now get or it’s been validated by Path Finder simply having added so much damn functionality. The fact that Path Finder has its own (crummy) Preview and Terminal replacements is offset by the fact that these — and many other — useful tools can simply be folded into panes in its windows.
Among the tools you can insert into the “info” panes are a terminal, process view, git and svn utilities, a permissions editor, hex editor, and an image rating/tagging tool. And of course you can simply hide these panes when not using them. Unfortunately, all of these various tools are kind of half-assed — useful in a pinch, but unpolished and unworthy of the overall application.
So, I’m pretty happy with the latest Path Finder, but unfortunately there’s still a big — huge! — problem. It doesn’t play well with Default Folder, which is simply the most useful utility application on the Mac, and has been since the mid-90s (when its competitors, such as Boomerang, fell by the wayside). Leaving this issue aside — and I wouldn’t be surprised if it leads to my giving up on Path Finder in the long run — Path Finder 6 is a very powerful and attractive application.
And, as for the latest MacHeist bundle — I got AirServer for $10, donated some money to the Nature Conservancy, and gave some worthy developers a bit of extra publicity. So I’d call it a win all-round.
As my reader knows, I’ve something of a love/hate relationship with Blender. Or perhaps it’s more of a need/despise relationship. If there’s ever a feature I need in a 3d program but don’t have in my current favorite, the answer is always “well, Blender does it and it’s free” (unless the feature is motion blur — Blender’s motion blur sucks … or it did last time I tried to use it).
My favorite 3d tool for the past few years has been Cheetah 3d, which has many virtues, a few flaws, and a lot of missing features. I think it’s important to differentiate between a missing feature and a flaw, the latter being a feature that doesn’t work as well as it should, or isn’t as easy to use as it should be. Blender, measured in the same way, has many virtues, a spectacular number of flaws, and not many missing features (that I can think of).
It’s worth noting that for any given user, sometimes it’s better to have a flaw than a missing feature (if you need that feature, however flawed), while at other times it’s worse (e.g. if that flawed feature creates clutter or confusion and you didn’t need it anyway). Although after over fifteen years of 3d experience I thought myself a pretty advanced 3d artist, I still have a lot to learn, and Cheetah 3d’s simplicity has helped me learn some of it. But, over time, Cheetah 3d’s missing features have become an increasing sore point, while my continued grappling with Blender’s apparent flaws has led me to better understand its significant, but less apparent virtues.
The real problem with Blender, it turns out, is that it has a lot of hidden modes. Most powerful software has hidden modes, and understanding those hidden modes slowly turns the software from incomprehensible to amazing as you have “aha” moments. Sometimes the developers of great software will recognize a few or many of the moments necessary to help you on your way and explain them to you at the right time minimizing the time it takes for you to reach nirvana. Sometimes developers will leverage your understanding of existing software rather than [gratuitously] create new paradigms of their own. The fact that Blender has done neither doesn’t make the software bad, merely the process of grokking it unnecessarily unpleasant.
It’s full of modes!
A lot of software today tends to be virtually modeless when used for common purposes. Modes were recognized as a bad thing in user interface design when Apple produced the original Human Interface Guidelines for the Mac.
Even so, the early Mac programs were very modal. For example, if you pressed command-F in MacWrite a “Find Dialog” appeared which was modal. You couldn’t, for example, select some text in the underlying document and paste it into the text field. If you were “finding” stuff and saw a typo you had to leave “Find Mode” to correct it, and then resume “Find Mode”. In MacPaint when you zoomed in you were in “fat bits” mode and the only tools you could use were the pencil and eraser. Much of the complexity in modern software has resulted from eliminating modes — in essence making all things possible all the time.
It’s not acceptable for a modern word processor not to offer all its formatting functionality in headers and footers when, once upon a time, you essentially entered a crippled mini word-processor to modify your header or footer.
The worst kinds of modes are hidden or implicit modes — i.e. modes you can be in without being able to tell. A classic example of such a mode is selecting stuff in Photoshop. If you “make a selection” that’s all you’re doing — making a selection. You aren’t actually selecting anything. If you then “lift” part of the underlying image (i.e. selecting that part of the layer underneath your selection) the user interface doesn’t change even though you’re now in a different mode. Understanding this odd behavior was, for me, the big aha moment in learning to use Barneyscan Photoshop. Before I figured that out, Photoshop just seemed perversely difficult to use.
And, in fact, Photoshop is perversely difficult to use. MacPaint didn’t do things the way Photoshop did, and Deluxe Paint (and later Studio/8 and Studio/32) managed to extend MacPaint’s abilities without breaking MacPaint’s paradigm to the extent that they allowed you to do everything Photoshop managed with its “selections as entities in and of themselves” without requiring users to unlearn their existing habits. No-one cares any more because every graphics pro knows Photoshop and has committed all the shortcuts for manipulating selections to muscle memory, but it’s easy to forget how perverse Photoshop seemed to people who knew how to use other graphics programs back in 1990.
To my mind, figuring out Blender requires at least two major realizations. Perhaps by documenting them I may help someone else “get over the hump” faster than I have.
The first realization is that Blender is built around the concept of a 3d cursor. You need to learn how to work with the cursor. (Shift-C snaps the cursor back to the origin, and learn to use the Shift-S menu — it’s wonderful.) The 3d cursor is a very powerful concept — analogous to a text cursor — but other 3d programs make do without such a concept, so realizing that Blender has this concept and is to a considerable extent built around it is analogous to understanding Photoshop’s concept of a selection as an entity of itself — once you realize that Photoshop is all about selections and learn how to work with them everything becomes second nature.
Aside: one thing I tried early with Blender was switching its mouse behavior over so that left-click selects and right-click sets the cursor. Unfortunately, Blender becomes somewhat broken with this option. In my opinion Blender would be a much easier program to use (and master) if left-click selected, and if — indeed — major thought were put into making more common actions left-clicks and less common actions right-clicks. This may be addressed (at least by preferences) in 2.50, but don’t hold your breath.
The second realization is that Blender is full of modes, that most of these modes are hidden, some modes stick to specific objects while others affect the entire program, and that in some cases which mode you can enter is itself a modality. This isn’t as easy to wrap in a nutshell — but it’s probably helpful to know that if Blender is acting in a weird or apparently unpredictable way, you’ve probably managed to trip over a hidden mode.
Blender is difficult, but most of that difficulty is necessary
When I say Blender is full of modes, these are modes in every sense — menus change, the way things are displayed changes, what you can select and do changes, etc. etc. etc.
And when I say hidden, I mean that how the user interface behaves can be completely changed by a setting on a panel you can’t see, or by the mode you previously got into when you had something else selected.
Here’s a particularly hairy example: there are two distinct animation modes in Blender, “Actions” and “NLA” (Non-Linear Animation).
The idea is that you animate a figure’s basic reusable behaviors (e.g. walking, jumping, waving) as individual “Actions” and then you build longer animations using the NLA window which treats actions as layers (much like video layers in After Effects or Final Cut Pro).
Whether you’re in NLA mode (where what you see happening and what you are modifying is happening in the non-linear animation context) or Action mode (where what you see and do affect a specific action) is not necessarily visible or apparent at any time. Oh, and, each action you’ve created is, itself, a different mode (and which you’re in is not apparent unless you happen to have the right display visible and the right hierarchy disclosed and scrolled into view).
Now, let’s suppose you’re editing vertex weights in the course of “rigging” a model.
What does this mean? Well, you’re trying to choose how the vertices in a mesh are affected by the movement of the bones in its animation rig — a virtual “skeleton” made of “bones”; the model is the mesh, the rig is the skeleton, and to say a model is rigged is essentially to say that it has had a skeleton built for it and has been attached to that skeleton using vertex weights).
Sounds pretty complicated, right? Well it is, and so it’s kind of stupid to expect the user interface for this to be simple or particularly straightforward. I think it’s fair to say that no similarly conceptually complex task is explicitly supported in, say, Photoshop or Word or Excel, each of which has a pretty complex user interface in its own right.
The usual way of showing bone weights is to show a “heat map” indicating how tightly bound vertices in a mesh are to a given (selected) bone. This is how the mind-bogglingly complex Blender does it. This is how the beautifully simple Cheetah 3d does it. But in Blender, to select a bone you … select the bone. In other words, you right-click (because selection is done by right-clicking) on the bone and voila. Pretty neat, huh? In Cheetah 3d you look for the skeleton deformer modifier tag in the hierarchy view, click on it, and then find the bone in a scrolling list in the properties browser.
Now, in Blender it’s important to make sure that the armature (or “skeleton” of the model you’re working on is in “Pose mode” — armatures can be in one of three modes) and then select the mesh and set it to “Weight Paint Mode”. If the armature is in the wrong mode, the mesh won’t be posted while you’re finessing vertex weights, which means you won’t be able to see whether what you’re doing is working. Also, you may not be able to directly select the bones you’re interested in. This is all horribly complex, involves hidden modes, and is utterly counter-intuitive. But the benefits (you can paint weights on a posed model and see the changes in real time, and you can select bones directly) are absolutely huge.

Eating My Own Words?
I’ve ridiculed Blender’s lack of usability in the past, and probably will in the future. Even some of my praise for Blender in this post probably seems close to ridicule. It’s a ridiculously — and often unnecessarily — difficult program to get into. Almost all of my complaints (and then some) are as true now as ever. There are so many simple things that could easily be fixed in Blender to make it easier for new users that it’s not even funny. The same was true for Photoshop when it came out, and — over time — Adobe changed some things to be less non-standard while others eventually asserted their dominance. Even today I’m pretty sure any Deluxe Paint or Studio/32 thinks that the keyboard shortcuts for Photoshop are idiotic compared to those for their cherished bitmap editors. I know I do.
The fact is that Blender is an incredibly capable, rock-solid piece of software (I can’t remember when it last crashed on me). Its user interface foibles are stupid and ugly, but you can get past them, and in the great scheme of things it’s certainly worth never having to pay for another 3D Studio Max upgrade or figure out how to replace that burned out ElectricImage dongle.
Who knows? Maybe in five years I’ll be writing a similar article about my newfound love of GIMP.
Addendum: Blender Hints
Simple things that may make Blender easier to use.
Oddly enough Preferences are accessed by “dragging down the menu bar”. WTF? Well, that’s how it works.
Having opened up preferences, you probably want to go to Edit Methods and go to Add new objects: (on the left) and turn off Switch to Edit Mode and Aligned to View which may be on by default (because they used not to be options). Aligning new objects to your view is hardly ever what you want, and many users have the shortcut for (a) switching out of edit mode, (b) clearing a newly created object’s rotation, and (optionally) (c) returning to edit mode burned into muscle memory.
You’ll also probably want to change your default directories to minimize the amount of navigation you have to do in Blender’s (horrible) file requester.
Once you’ve learned how to create a nice setup in Blender you may want to build a good default scene and File > Save Default Settings.
Often, especially when going through tutorials, there’ll be reference to a command that I just can’t locate in a menu. If the command has a hotkey you can find it using the Hotkey and Mouse Action Reference (Help menu) — which has a search command. Then you can at least find out the keyboard shortcut, even if you still won’t know where the heck to find it in the menus.
The Essential Blender (book) is really very good, although it does contain quite a few errors (so if something just isn’t working, maybe the command’s name or the keyboard shortcut is incorrect).
If a bunch of things suddenly disappear or become uneditable you may have inadvertently messed with the scene layer settings (which the standard number keys are shortcuts for, so it’s easy to do). If you don’t use layers deliberately the chances are pressing 1 (above the Q, not on the numeric keypad) will restore everything. If you do then you’ll already know how to deal with this.
Armatures and bones have their own independent layer system, so be prepared for completely orthogonal confusion when working with rigs.
In many cases, Blender reuses key commands in different contexts. E.g. G (grab) is used to move objects in 3d, keyframes in the Action editor, and action layers in the NLA window. N (transform properties) brings up a numeric transform floater in 3d views, and similarly useful floaters in (some) other views. A (select all/nothing) selects all or nothing where appropriate, in the hierarchy view it collapses/expands everything.
It’s well worth learning “root” shortcuts which bring up menus. E.g. Shift-S (“snap”) brings up a menu — usually the next number you type selects the commands (in order) in that menu. In some cases (e.g. G and R) you can press X, Y, or Z to constrain your action to an axis.
Keyboard commands in Blender apply to the panel the mouse is over, which can be very confusing (especially since each pane has its own menu bar and hence its own keyboard shortcuts).
Selecting things is an action (which you can undo). Changing a view is not an action (and you can’t undo it) — unless you moved a camera.
Blender’s camera controls are pretty annoying (absent?), but if you manipulate a camera object in a 3d view with the transform orientation set to “Normal” or “Local” you can dolly the camera around in a relatively intuitive fashion. (If there’s a command to, for example, create a camera from a current user view, I haven’t found it. Shifty-F lets you fly a camera around, but when you leave Fly mode your camera is back where it started.) Edit: a reader notes that Ctrl + Alt + 0 snaps a selected camera to the current view, which is very handy.
I use Blender on a (Mac) laptop quite a bit, so it’s worth knowing the view navigation controls for folks with no MMB (middle mouse button). Option-drag to orbit, option-shift drag to pan, and scroll-wheel (which Mac laptops do just great) zooms.
Blender supports “virtual screens” internally — three complete viewport layouts (more if you want) that can be accessed via control-left and control-right. Very handy given how cluttered things can get.
The render buffer (F11) can be zoomed and panned using the usual keyboard shortcuts. There are actually two render buffers (containing the current render and the previous render) and you can toggle between them with the J key (very useful for checking what effect that last tiny change had). Click and hold in a render view for an RGBA value.
Note especially for Unity developers: the FBX exporter “bakes” subdiv modifiers (at “render” level) into meshes on export, so beware!
And there’s a ridiculous number of useful tips and gotchas here.
