Hi Stuart,

This is just a quick message to say I've had some luck over the weekend.
I've finally got my textured cube up and running!

I'm still not quite sure what I did though, so maybe you can help me on
a few questions (I hope so, anyway, because I really feel I'm on a roll
now!).

I used breeze to create a simple cube.DXF file and then converted it to
RSD using DXF2RSD -dup (without the -dup, some of the sides of the cube
seemed to pop in and out of existance once on the PSX. Why is this?)

I then used timtool to give once face of the cube a texture, and saved
it.

Using rsdlink I managed to create a .TMD file which I could display on
the PSX no trouble, with all sides visible. However there were a few odd
glitches. First off, no texture. Second, the cube occasionally showed
little triangles appearing on some of its sides as if part of the cube
behind was being drawn there. The triangles popped in and out of
existance as I rotated the cube.

To fix the texture problem I looked at the "CAR" example and loaded one
of its textures into timtool to see were in the VRAM graphic it
appeared. I then cleared this out and loaded in my texture to position
it at the same place, but not really knowing why. After saving it and
doing rsdlink again, it worked!

How do I know where in the rsdlink VRAM display to put my textures? I
know from the info output from rsdlink that the texture was at texture
page 0, but the "slot" in the VRAM display of timtool was something like
10, so what's the correlation?

I hope I've explained this clearly enough. If you could give me any
extra help in this regard, I would be very grateful. A few weeks ago I
was all set to give up on Yaroze as I was getting nowhere, but thanks to
you I'll definitely be pushing on. It takes me back to the time I used
to spend hours programming the Amiga 500! Great fun.

Thanks once again.

	Jon.
