I am having a problem with selecting portions of my model for HD polypainting. I have HD subdivided a model of mine to 42 million polygons and polypainted a torso using the HD geometry, but for some reason now whenever I hit A and select a portion of my model the geometry explodes. Is there a way to stop this happening? It seems to happen at random, I can paint for around 10-15 minutes and then I have selection problems, then sometimes they go away and come back. If anyone could help it would be greatly appreciated, thank you!
