Max weights per vertex?

Is there a max to the number of weights per vertex?

You're saying the offsets buffer is 32 bit packed? Or just packed on disk? It doesn't seem packed when iterating over the runtime dataset.

rr-reinhart Sorry, Spinebot's answer is incorrect, one vertex can obviously be affected by the weights of more than 4 bones. The thread to which Spinebot refers is below:

There is basically no limit to the number of bones that can affect a single vertex, but it would be computationally inefficient to have a single vertex affected by a large number of bones, so it should be limited to about 5 or 6 at most.

Great! That helps. In that case, I won't bother putting this stuff into the vertex buffer. I'll just use the vertex buffer to store the offset index and the number of influences and bind a third buffer that contains the meshes offset/positions. I mean, in my head it totally makes sense! Thanks!

Are you working on GPU skinning? Do tell how that works out. Last time we tried, it didn't make much of a difference, as it breaks batching (at least with the encoding schema we used. That was OpenGL/WebGL though, ymmv with other graphics APIs like Vulkan, D11, or Metal)
