Why does setting a non-zero Bound.center move meshes?

Hi all, I've been playing around with Graphics.DrawMeshInstancedProcedural, but I've ran into an issue with the Bounds parameter. Whenever I set the Bounds.center to any non-constant amount, the mesh is moved by a corresponding amount. To illustrate this, here are 64 chunks rendered with GraphicsDrawMeshInstancedProcedural.



Each quad is rendered with its own separate call of the Graphics.DrawMeshInstancedProcedural method, and each Bound.center is set to zero. However, when I set the Bound.center to the midpoint of each chunk this happens:



Since, as I understand it, the Bounds parameter is only telling the GPU if the mesh should be rendered not where the mesh should be rendered, why does Bounds have any effect on the position of the mesh being rendered?

 

Any luck on this?

 

No, I originally planned on using Bounds as a sort of culling method, but I realized I could just do that myself and stopped looking into it. Looking back on my post, I think the issue is that I was setting the Bounds center vector3 to the midpoint of the chunk instead of the chunk's origin.

 

Interesting.
