Unity: skinned mesh vertexbuffer output slightly different than correct results

Question

It’s like this hip is stuck in place, with in the pictures(being at different times in the animation since I can’t upload a gif) the red wireframe is the drawing of the raw output triangles and everything else being default unity, aka the correct output What am I doing wrong? What am I missing? This has been driving me nuts for 2-3 days now, any help is appreciated

Answer 1

As you do not post any code, I will try to do some guessing over what is going on. Disclamair: I actually happen to run into similar problem myself.

First, you must know that Update's of MonoBehaviour are called in random order (not neccessery random-random, but yous see the point). If you bake mesh in one component, it can still be one-frame late to the Animator component.

There are actually two solution of this case: first is to specify the order of Script Execution Order in Project Settings, while the second is to use LateUpdate instead of Update when updating mesh after skinning.

The second problem you might have run into is scale / position of skinned mesh. Even if it does not contribute at all to the animation movement it can still wreck the mesh baking collision later on.

To fix that make sure that all your SkinnedMeshRenderers objects have Local Position, Local Rotation and Local Scale set in Transform component to identity (0,0,0 for position and rotation, 1,1,1 for scale). If not - reset those values in editor. It will not change animations, but it will change mesh generator.

If both solutions does not work, please describe the problem more thoroughly.
