The VRAM is 1024x512, so x=0 y=512 is not valid, hence your problem.

Hi!

Howz the weather over there?
(tis rather nice here on the coast of Aussie)

I have a question as I am experimenting with Textures...

Please forward it to the programming/3d_graphics news group.

I find that setting the texture page between 0 and 7 is fine
using the coordinates 0 for y and multiples of 64 for x in the
frame buffer.

I am using resolution of 512 x 256 for a frame, 512 x 512 in
total for both (double buffered) frames. I am loading my
texture at x=0,y=512 and setting the texture page in my model
to 8 assuming this is the correct texture page as a model
may have a texture id in the range 0 - 31 only making me
assume that in my situation x must be a multiple of 64 and
y is a multiple of 256.

This does not work (as you may have guessed). I have also
been experimenting with the drawing environment structure,
setting it with texture rectangle sizes, etc but this does
not appear to have any effect.

Using GetTPage() with an appropriate x,y returns 32 for a page
id but the model's texture page must be in the 0-31 range.

What's going on here?

Thanks in advance...
