Hi Theo,
I attached the ply file. Simply displaying the mesh did not work. I have tried other simple ply files as well. I replicated the problem on another machine and confirmed that ofv9.0 seems to have an issue loading in colors from ply files. Actually, if I look closely at the point cloud, lighter values seem to be a very dark shade of green, although everything generally looks like black.
I was able to go back to ofv8.4 to display my point cloud colors though. I just hope there's a fix for 9.0
