My untextured mesh normally appears all white in potato mode but one of my models has purple patches on it. The normals are fine and I can’t see what’s wrong. Also, sometimes my real-time textures are messing up. They flip between messed up and ok when zooming and selecting stuff - is this an ATI thing? Here are some screenshots (hit return in the location bar if the page fails):
Thanks R2Blend, it appears it is. Funny, I don’t remember painting any vertices. I must have painted one vertex by accident or something and then just kept extruding it. %|
Does anyone know about the textures messing up? My whole Blender window goes like that when I render and in the new version when I go into the dock. Like this:
I have an ATI Radeon 7500 mobility with 16MB VRam. I’ve turned off mipmapping/antialiasing in the user prefs but I think I did that before and it made no difference.
It’s hard to tell what’s causing it because it’s intermittent. Sometimes it goes away if I restart Blender. The thing is, a few OpenGL programs I made did this when I maximised them. Blender does it more often. Very puzzling.
Do you get a similar effect with your card? I didn’t think it was the card because I can play most low-end games at a decent fps - I managed to get Soldier of Fortune 2 to work a while ago but only just.
I think you’re right though, the textures only seem to mess up when I do something else that uses OpenGL and since nearly everything in Mac OS X uses it including the interface, pretty much everything I do affects Blender at some point. I suppose I could use 16 bit colour but I’d rather suffer the intermittent problem - it doesn’t happen too often. I was just checking it wasn’t an ATI driver issue because a few people have had trouble with them.
uv-mapped objects turn pink if you have an image assigned, and then remove it (so that blender doesn’t find it any more). happened recently to me - i was browsing some older files with “outdated” image references (either moved or deleted textures).
