Right, this is how it’s supposed to work:
This scene has 6 model componens - 3 with one .glb file and 3 with another .glb file. Each model is referencing multiple meshes (~10 meshes per glb file). With instancing this means that we should be able to render all sub meshes for each model in one draw call:
Here you can see that the heads of one of the model is getting rendered all in one go, which is what is expected.
There is a PR currently for the batch key change, so I’ll let you know once it’s been merged to beta
