I canāt 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 donāt have that kind of information, it wonāt use GPU instancing
Thatās 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 āinstanceā is used for all nodes
Thatās all I needed really, I might have mixed up instancing with gpu instancing
by user 103054507105067008
?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
Weāre not duplicating data or anything
So in other words āwhat you put in the file is usedā
If thereās 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 donāt mean āpreviewā but basically āshow statistics about data in the fileā, 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 ā¦
