On top of everything you've...Bravo, Aligorith!<br /><br />On top of everything you've just said, I would also point out that driver variables allow the user to easily express more complex ideas via different variable types. So, for example, the distance between two bones in either local or world space, which would be an enormous pain to express directly in the driver expression!<br /><br />All-in-all, this is an extremely useful and powerful system, and I am very grateful for your work on it!Cessenhttp://www.cessen.comnoreply@blogger.comtag:blogger.com,1999:blog-1978356510587112308.post-47588759935334780292011-10-01T13:56:11.249+13:002011-10-01T13:56:11.249+13:00Oh, regarding Houdini, I just meant that people ha...Oh, regarding Houdini, I just meant that people had just been lusting after using node trees to define their rigs for years.<br /><br />As for the depsgraph: well for a few years I've been kindof reluctant to touch the thing, even though I know it does need some work, just due to the difficulties in the task. <br /><br />A few years ago, some of the frontend tools were more important to improve than the depsgraph, which comparatively few would run into troubles with. Furthermore, tackling the depsgraph issues is a project in itself - something that would have meant possibly delaying the introduction of improved tools that bring us up to speed with the rest of the world first.Aligorithhttps://www.blogger.com/profile/11379156223939123157noreply@blogger.comtag:blogger.com,1999:blog-1978356510587112308.post-47602491034000292982011-10-01T02:32:43.859+13:002011-10-01T02:32:43.859+13:00great post, and totally relevant to good(advanced)...great post, and totally relevant to good(advanced) rigging practices. When oh when will we get a decent depsgraph? The issues with the updating of drivers and constraints is a fairly major weakness with blender ATM, and its odd the number of years that its gone, imo, mildly unaddressed. I too end up using variables and/or writing pyScripts to force frame changes & updates just to have my rigs actually pose as they should on a given frame.<br /><br />back to the post, regarding your point on houdini, you can AFAIK use variables and functions(in code) to define input sources for nearly any type of node, rig or otherwise (even changing them dynamically on a per-frame-basis, in code, or with "switch" triggers), so not sure what you meant there.3duaunhttp://du3d.orgnoreply@blogger.com
