Applying modifiers doesn't seem to work for it . Is there any way to export gltf format When I use geometry nodes?

When you use the export dialogue in File>Export>GLTF make sure to also choose apply modifiers in the export options. Then the GN modifier will be applied on export rather than the input geometry only.

  • $\begingroup$ Ah, @scurest has the answer: If you add a "Realize Instances" node, you can get "Apply Modifiers" to work. github.com/KhronosGroup/glTF-Blender-IO/issues/… $\endgroup$

Try this:

  1. Export animation as alembic .abc with face sets option activated for material support.
  2. Import .abc on Blender.
  3. Bake animation with Object > Animation > Bake Action > Visual Keying to Object.
  4. Export as .gltf
