How to export/load custom VRMA?

[Benjythebee]

To test importing VRMA animations, I have this FBX boxing mixamo animation.

I transformed it into a VRMA using VRM Addon for blender (blender 4.2)
This is the output: https://github.com/Benjythebee/three-vrm-cache-repo/blob/master/cheering.vrma

Loading the VRMA output into this three-vrm example just doesn't work.

Do you have a way to make advanced animations work as VRMA?

Please add tag "discussion" if possible

For reference, I made an issue in Saturday06's Blender Addon just in case

@Benjythebee It seems that the y component of the hips position is approximately zero, which means that the animation is not T-posed appropriately.
I'm pretty sure you have to fix the animation side on Blender.

The animation is straight from Mixamo though

The conversion in the Blender side is not performed correctly I believe. Make sure your VRMA transforms follow the VRM T-pose specification, as the VRM Animation spec says.

By the way, we intended to provide an appropriate warning when loading such files, but we failed to do so. We fixed the warning in #1525 .
