RenderExistingMesh causes GC Alloc

kido0617

Hello.

When I Use RenderExistingMesh Component, I noticed that GC Alloc is occurring every frame.

When calling sharedMaterials, using GetSharedMaterials can avoid GC Alloc.

Material[] parentMaterials = referenceRenderer.sharedMaterials;
(Line136, RenderExistingMesh.cs)

I'm sorry if my point is wrong.
Thank you.

Using version.
Unity 2022.3.27
Spine 4.1

@Harald

Thank you for quick fix!
But it seems the sharedmaterials part of UpdateMaterials, which is called every frame, is not fixed.
Is it possible to fix this line?
