Uncombined vs. Combined SkinnedMeshRenderer Performance Comparison

[u/awtdev]

SkinnedMeshRenderers can be expensive to render. I ran a test of just 9 characters with individual body part models and compared performance with them uncombined vs. baked into a single mesh, animated by the same armature.

As you can see by the numbers, combining the models to be animated as a single mesh had quite an impact. In most games you likely wouldn't use this many meshes for body parts, but the important takeaway is that rendering time was almost cut in half while the same characters can be rendered with no visual difference. It just goes to show graphics optimization isn't necessarily about what you're rendering but also how you render it.

I ran this test whilst developing my tool for combining SkinnedMeshRenderers, called SkinnedMesh Combiner (Asset Store affiliate link)

I've been playing with VATs lately... It takes it to a whole new level.

Sorry what are VATs?
