Bump maps - Bump depths
Hi All, a few days ago something weird happened and I can't figure out what I did, but basically the bump depth value acts in reverse of what it should do. Normally, as of a few days ago, any dark areas in the bump map would cause a bump to stick out of the surface in the direction of the normal, but now, with the same default setting it goes in the opposite direction (looks like a hole instead of bump). I can correct this if I put a negative bump depth value, or if I inverse the bump map texture under effects. But there has to be some setting in preferences or something that deals with this. This issue happens with any new projects or any new objects with bump maps that I create, if I open an old project that worked ok it still does the bump mapping the way it should. However, if i create a new object in that old project, the old objects would produce the correct bump, but the new object would not...
Anyone has any ideas?
