I've discovered Mixamo very recently. I plan to use its auto-rigging capability on all my unrigged characters.
The download option can either include the skin or just obtain the animation.
My understanding is that an animation is "simply" applying a composite timeline where each bone is modified separately.
Am I right to believe that downloading an animation from Mixamo makes it compatible with every Mixam-rigged character? Or am I to download the same animations for each variation in my skeletons (arm length, hip width, neck size, etc.) ?
Quick heads up: Mixamo
Mixamo is an auto-rigging tool. For instance, this Blender character will be imported as a .zip (containing my .obj and .mtl)
You are just expected to place the following colored circles on your humanoid:
After the auto-rigging completes, you can either download your static, rigged character (as an .fbx) or animate it using one of the many free animations. After applying an animation (one at a time), you can either download the character (mesh) plus its anim or simply the bare skeletal animation.
