The problem has come back again in all graphics modes (except legacy D3D which shows the points as tiny pixels and runs much slower)
It seems to be quite specific though: only the existing corona proxies in the scene fail to display as point cloud. If I create a new CProxy and load the same .cgeo file it works fine.
So for now I can do a clone+align of new proxy objects, but would be good to know if they will randomly stop working again as it does make my scene considerably slower if I have to set everything to full mesh view.
Any ideas?
Thanks,
John
