yes that should work… but actually not. another blender bug makes the Realize Instances node removing all UVs, which is unacceptable for exporting currently the only(?) way to export them is to manually breakdown instances into thousands of objects by the Make Instances Real operator, then join them… weird and laggy workflow this is not really related to the exporter tho, thanks anyway

FYI: I’m writing an addon that allows to export instanced geometries created with geometry nodes as glTF + EXT_mesh_gpu_instancing extension https://github.com/takahirox/glTF-Blender-IO-EXT-mesh-gpu-instancing It started to work.
