As I understand it, a mipmapped texture is composed of several levels, which are copies of the texture at different resolutions (so you can choose a level based on how far away from the camera the primitive getting the texture is), so the total texture size in terms of memory is the sum of all the texture levels in the mipmap. > > A couple of things to check: the memcpy in mach64UploadSubImage.

Sure, maybe I missed something before. At any rate we can try to get single textures working right before dealing with multitexturing. > > > Jose Fonseca > > > > -- > > Leif Delgass > > http://www.retinalburn.net > > > > José Fonseca > > _________________________________________________________ > Do You Yahoo!? > Get your free @yahoo.com address at http://mail.yahoo.com > -- Leif Delgass http://www.retinalburn.net _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
