Hi all,

I believe this should be in the 3D newsgroup but it doesn't get much
attention, so:

Does anyone know how to set up repeating textures for TMDs? I have set up a
texture window using GsDRAWENV around my texture, the idea is that if my
coordinates go outside this texture window the texture should repeat up
untill the coords are met. Thing is this does not work. My set up is:


setRect(&GsDRAWENV.tw,standTex.left,standTex.top,standTex.width,standTex.hei
ght);

Then I set up the U and Vs on the primitive, i.e:

 primPtr->u0 = 0;
 primPtr->v0 = 0;
 primPtr->u1 = 32*10
 primPtr->v1 = 0;
 primPtr->u2 = 0;
 primPtr->v2 = 96;
 primPtr->u3 = 32*10;
 primPtr->v3 = 96;

This should repeat the texture 10 times as I multiply the width of the
texture (32) by 10. Becuase there is a new texture window set up in VRAM I
reference only this window thats why no matter what X position in the VRAM
the image is as long as the .tw value of GsDRAWENV is set to that specific
texture the top left will always be 0,0.

Anyone have any ideas why its not working? All i get is the typical garbled
up corrupted texture.

Thanks in advance,
Max

P.S. When figured out this will also go in the DTMD mini tutorial.
