[Bf-committers] Armature preset

[Vilem Novak]

The fact this is being done is great news.
I have just some brainstorming ideas to add - 
I propose 3 levels of rigs - 
1-just deform bones
2-constrained
3-with secondary additions(muscles, some automated stuff for secondary motions e.t.c.)
the first level would be good for export to game engines, where you would animate with constrained rig and export use baked animation for the first level rig in game.
level 2 is for animating
level 3 has main difference in fact that it can include softbody elements and other time dependent things which are computed for rendering.

Other good thing would be animation transfer capabilities- so if more templates for rigs exist, the (main) deform bones have the same names, so that animation(more probably baked animation) can be transferred to other rigs. - This leads also to the idea to have the rigs capable of fast constraining to outer rigs, mapping to bvh e.t.c. in some half automated way. I'd be willing to make some prototype of a compatible ragdoll rig - this can then be used to blend in with standard animation, where you'd e.g. apply the endpoint of the animation as impulse for simulation and then blend the baked simulation from the ragdoll rig back to the animation rig..
Cheers
V.
