I use UMotionPro and love it. Thanks for the great assets.
UMotionPro currently supports only fbx files imported into Unity (I think it is identified by UnityEditor.ModelImporter)
Is this restriction of only fbx files mandatory? For example, is it technically possible to use UMotionPro for a prefab character created with a gltf file and a custom importer?
In Japan, there are many projects that use character models in vrm format using UniVRM (https://github.com/vrm-c/UniVRM). This UniVRM is serialized in preflab format.(but it is very similer to fbx humanoid)
Many Japanese developers would be very happy if UMotionPro can apply PoseEditor to prelab as well.
