I'm not sure I understand. We should advertise GL_MAX_TEXTURE_SIZE such that N textures of that size can be accomodated (where N = num texture units). Proxy textures are another approach, but not too many apps use them. -Brian ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
