This should also be handled correctly I believe. See the comments about "parity issue" in vbo_copy_vertices(). Essentially the code ensures the new buffer always starts on an odd triangle. (Though on a quick look I wouldn't be able to tell if it's all correct but it probably is as otherwise there'd probably have been bug reports about it.) -- You are receiving this mail because: You are the assignee for the bug.
