Mipmaps failed with Texture-Flag 256

I´ve tested this on various Computers with different G-Cards and drivers. If you set flag 256 ( store in Vram), Mipmaps does not work. LoadTexture "test.bmp",1+8 works correct LoadTexture "test.bmp",1+8+256 works not correct Any ideas? Is this Blitz or the drivers/G-cards? Shodan

From memory mip maps are not supported with texture flag 256.

This is one reason why flag 256 makes writing to the texturebuffer much faster: mipmaps don't have to be updated. You can't have both.

try to use dds... they are stored in vram and you have the option to enable mipmap. dxtbmp : http://www.mnwright.btinternet.co.uk/programs/dxtbmp.htm cheers, chi

Unfort. dds textures TextureBuffer is always zero.

Now i know something more about mipmaps and Vram. Thanks folks :-) Shodan
