Is there a reason this limit still exists? Is it impossible to change this limit, or is it just not important enough?
I think the technical reason is the “colbits” vector which is 16 bits long, but this could be changed… there are only about 40 lines containing “colbits” in the whole blender code, after all. Or would this break existing .blend files (I am not sure I understand SDNA)?
Can someone enlighten me on this?
