Bug report: cannot save animation after exporting #557

Open czpcf opened 2 months ago

czpcf commented 2 months ago

I imported a vrm model, added some keyframes and exported it as another vrm file. However, when I reopened it, the keyframes did not exisit and only the first frame was saved.

But the animation was correctly saved when I used the sample models(AvatarSample_A, B, C) from vroid studio. I wonder that is it related to some license issue?

I converted specification from vrm0 to vrm1 and solved the issue

Exporting animations in VRM0 is not supported.

VRM0 requires the normalization of bones, and the normalization of animations must also be performed at the same time. For this reason, exporting animations requires full implementation, and the implementation cost is very high. For this reason, even if it is implemented, it will be a long way off in the future.
