No. TakeBuilder is not a procedural animation generater.

TakeBuilder works by taking your existing character animation clips (like a walk cycle or attack animation) and applying them along a path or at specified locations you define in Blender. It is not an animation generator that creates new animations from scratch (e.g., it won't create a walk cycle for you). You need to provide the source animations.

Yes, you can use TakeBuilder with various character rigs.

However, if you need to use animation clips created for one character on a different character with different proportions or even structures, you will first need to "retarget" the animation. Other Blender add-ons specialize in handling this retargeting process before you apply the animation using TakeBuilder.

You can define a path for your character that changes elevation (going up or down). However, the tool is currently not smart enough to automatically align the character's footsteps onto the ground.

You would likely need specific animations for such surfaces or manual adjustments.

A basic alignment feature will be implemented in the BETA cycle.
