# Does the same material in multiple meshes consume GPU memory multiple times or only once?

My question is as the title suggests.

The situation that I’m facing is here:

- I have one SkinnedMesh loaded from a GLTF model.
- I want to render it as two models cloned by `SkeletonUtils.clone`.
- they have the same material with the same uuid, but I want each model to get a different pose.
  - so I can’t use InstancedMesh.

- I checked GPU memory usage in chrome task manager. It seems it consumes once.
  - adding a cloned model into the scene doesn’t increase GPU memory usage.
  - but I wasn’t sure, so I post this question here.

Yes, the material is shared across all meshes that reference it.

If you alter the material, all meshes get the change.

Thanks a lot!

could you give me a doc, an explanation, or source code to help me understand this If you know?
