aha that works aswell, i found my old method eventually too,you can use this:
SET OBJECT TEXTURE Object Number,Texture Mode,Mipmap Flag
as far as i can tell, set the Mipmap Flag to anything but 0 and the texture detail goes blurry.
ps. texture mode flags:
0 - default texture setup
1 - reflects the textures in a way that gives you an endless seamless texture (quite useful)
2 - takes the colour of the pixel at the edge of the texture and uses that beyond the bounds of the first texture. (not quite sure what that would look like)
Brains are for idiots.
