GPU instancing extension support?

[jessearmandse]

Hello,

I was trying to load a simple model that supports EXT_mesh_gpu_instancing, as can be seen in SimpleInstancing model.

Also, found out that there are at two fixes related to this from cgltf #185 and #216.

I applied those fixes, then tried to load the model again, but what I see is this instead:

However, the model can be loaded normally in three-gltf-viewer, as can be seen here:

Any idea what's wrong, and what could be done to load and render the same model?

What's wrong is that we don't support EXT_mesh_gpu_instancing yet, and neither SceneKit nor RealityKit support instanced user attributes, so adding this will take some work.

Preliminary support for mesh instancing is available as of 6c4d05d and will be incorporated in a forthcoming release. Any feedback welcome.

Right, I discovered that it wasn't supported after looking through the GLTFSceneKit. Thanks for the quick response, I'll try out the changes.

This enhancement has been incorporated into the 0.5.9 release.

This issue will be closed as completed in 7 days if no further feedback is received.
