I get black sections around transparencies, like some prim hair that I bought. The thin parts of the flexible rectangles that make up the head of hair or pure black, while the wide sides show the texture (with transparency when appropriate.) How do I get rid of this? I recently installed a new NVidia GeForce that SL said was "not supported". I guess it is too new. Is there some other way to work around this problem, besides getting a different video card? The drivers are up to date. My computer is powerful enough. I have enough bandwidth. EDIT: pic here: http://www.flickr.com/photos/14359698@N07/5620671612/ EDIT: The video card is an NVidia GTS 450. SL2 viewer, Windows 7, AMD Phenom Quad processor, 4GB RAM EDIT: Disabling VBO did not work. Edit: It only happens with some textures. I can't seem to edit the colors: The texture is hair, changing anything takes away the hair.
