Skeletal mesh twisting #5

Closed ndrewfrost closed 4 years ago

ndrewfrost commented 4 years ago

I am having an issue importing the animations into unreal, the mesh is twisted when importing the animation. (Imported animation attached left, no animation on right) image

I imagine there is some step that I could take to fix this. I would really appreciate some help.

My steps were :

Autodesk FBX converter for FBX model to FBX Binary. (This model imported into unreal with no problems) Open the bvh animation files with blender. Add a root node to the animation skeletons. Export as a FBX Import into Unreal attaching the FBX model skeleton as skeleton.

Hi,

Unfortunately, for this dataset we do not use other animation softwares other than MotionBuilder, so our tests and support are limited to this pipeline, but welcome any contributions that could solve these issues.

We confirmed that simply copying the animation data of an imported BVH onto the FBX skeleton works as expected in MotionBuilder.

For now, we can only suggest to check if the coordinates convention in the chosen software matches what's in the BVHs (i.e. Y up) and that the rotation order also matches (i.e. ZYX).
