I believe there’s already an issue opened for the KhronosGLTF exporter, it sounds like they’re still working on supporting multiple animations https://github.com/KhronosGroup/glTF-Blender-Exporter/issues/112
I tried the alternate KupomanGLTF exporter and it was able export all of my animations, except they were all distorted in the engine as if I hadn’t applied the location/rotation/scale in blender, so that didn’t work either. This was about 2-3 weeks ago though, so maybe something has changed with their exporter since then
@nehon I didn’t know about the Sketchfab workflow, but that sounds like the best way to export multiple animations at once for now , at least until the blender GLTF exporter is updated, thanks!
Edit: it does look like there’s been some update on the issue with the Khronos GLTF exporter since i last checked https://github.com/KhronosGroup/glTF-Blender-Exporter/pull/166
