I can’t see the ?debuginstancing working in my model viewer here using this test model for instancing drag/dropped into the window, what am I doing wrong?

Instancing needs to be enabled on your materials in Unity / Blender when exporting with needle
This file is just a regular GLB where materials don’t have that kind of information, it won’t use GPU instancing
Ah, is there a workflow for exporting instanced meshes in a glb file here? As in gltf.report recognises one mesh from the file so instancing is working there
by user 103054507105067008
That’s something different
Yes, there is one mesh there, and the same in Needle
Oh good
by user 103054507105067008
All nodes will be using the same mesh
So in a sense the mesh “instance” is used for all nodes
That’s all I needed really, I might have mixed up instancing with gpu instancing

?debuginstancing shows you GPU Instancing in use, so basically many objects being rendered in one draw call using instanced indirect
Is there a url parameter for regular instancing?

Not sure what you mean! If the nodes all use one mesh then they use one mesh
We’re not duplicating data or anything
So in other words “what you put in the file is used”
If there’s 20 cubes with unique meshes each then you get 20 unique meshes
If the 20 cubes share the same mesh then, well, they share that mesh 
Just wondered if there was a way to preview that but no worries if not I can use gltf.report

I see 
by user 103054507105067008
So you don’t mean “preview” but basically “show statistics about data in the file”, right?
Yes

You can do that with either https://gltf.report or https://viewer.needle.tools or babylon sandbox or gestaltor or VS Code or …
