[Bf-funboard] AnimationLayers and Simplifying Nodes

[Juan Pablo Solís]

I think you get the idea better than me, it would be great if we make an animation and the client says the walk cycle is too slow, then we make a layer including the bones and the segment of the walkcycle and get it short to make it faster, and if them tell us, "mmm please put an anticipation before the character jumps" then we make some layers, get the walkcycle layer, and move the jump layer (or group, or action) along the timeline, and start working with the anticipation movement in the middle. Something like that, you seen to know more than me about this, i´ve just used maya and blender for animation and them do not have something like this, when i´ve had to correct animation, i´ve had to move selection frames and then sometimes get to time them again.

well i think that the addition functionality could be that them are gouped
I think I know what you're talking about.  It seems to me the question breaks down in to two parts.

First is the ability to, as you say, stretch or shrink a selection of keyframes so the range of time they take up is longer/shorter then the original timing of the keyframes.  I think this is already possible in the action editor.  Select a bunch of keyframes then scale it using "s".  The current frame serves as the center of this scaling so you'll want to make sure your current frame is the frame you want to scale from.

The second part is the part about grouping different tracks together inside the action editor.  I suppose this could be helpful if you have a model with hundreds of bones which you need to organize.  For instance, say you can have groups for the arm, leg, face, etc.

But I have a feeling this is not what you're looking for.  I think what you're looking for is an "onion skinning" like system similar to what's available with Character Studio in 3DS Max.  But this is actually layering and blending of discreet animations clips on top of each other, kind of like an editor for actions which are layered on top of other actions which may or may not share keyframes for same set of bones.  That is to say, a "group of tracks" inside the action editor wouldn't be able have one bone belong to more then one group where as an "action layering system" would have keyframes for a bone in "action 01" which blends/overrides with keyframes for the same bone in "action 02".

As far as I know this kind of functionality is not available in Blender yet.(Someone please correct me if they knows this to be incorrect because I would love to know. :D)  This kind of functionality would certainly be a useful one but it's probably a pretty involved project if someone wanted to tackle it.

phong.
