Question by user-1613 (google) · Jan 07, 2011 at 05:04 AM · proceduralskinningskinned-mesh

Procedural Skinned mesh?

I understand what the SkinnedMeshRenderer does. I also understand how I can create a Mesh, and have it rendered through a MeshFilter. However, what I want to do is create a skinned mesh -- at runtime. The mesh class has vertex channels for position, normal, texture coordinates, color and tanget, but no vertex channel for bone index or weight.

Suppose I have a game that will download data at runtime, and this data will be in the form of a vertex buffer that contains position, normal, texture coordinate, bone index and bone weight data. How should I go about rendering this data in Unity? (I don't want to calculate the skinned mesh output "by hand" in JavaScript or C#; I want to use the built-in optimized skin rendering)

Yes, it does. Mesh.boneWeights, also Mesh.bindPoses; see the docs.

I will read the docs, right after I return from my date with the optometrist :-) I guess I was reading old/incomplete docs (not the actual reference docs). Thanks!

How old? :) I think $$anonymous$$esh.boneWeights has been in there since Unity 2.0 or thereabouts.
