Spine, SkinnedMeshRenderer and draw calls

pavel_j

Hi,

Our animators made character animation in spine, exported it in to unity and backed it to prefab. Number of character's parts use SkinnedMeshRenderer and number use regular MeshRenderer. According to documentation Unity can batch meshes that used by MeshRenderer only and it leads to high number of draw calls. How can I get spine's export that use MeshRenderer only ?

I think you can export it to a separate skeleton for each skin, then delete the skins.

Clarification:
https://docs.unity3d.com/Manual/class-SkinnedMeshRenderer.html
SkinnedMeshRenderer is Unity's renderer for Transform/bone-weighted meshes— "skinned meshes", in generic 3D modeling terms, hence the name.
It is the translation of Spine meshes with weights. In Spine, the term "Weighted" was preferred to avoid confusion with "Skins" feature.

Fix:
If you don't want SkeletonBaker to generate SkinnedMeshRenderers, remove all weights from your Spine skeleton before baking.

(I hope you understand the limitations of baked/converted skeletons though. It's not fully featured. It's not the primary way to use Spine-Unity and many Spine features will not work.)
