How to use sprite_animation_UV in shape_keys_animation on godot 3d?
enter image description here
I have a simple shape key animation made with blender, and use animation UV (50 frame) for the material texture.

But I don’t know how to export it to Godot engine?

GLTF 2.0 just don’t support animation UV, and I try to export models as a mesh to Godot and UV unwrap in there, but I don’t know where is animation sprite UV.

Sprite animation and mesh just like two independent stuff that cannot combine together.
