I don't know exactly what you mean by the texture shifting but flyrawgui gives you exactly what you create, no slicing and spacing - which is for terrain anyway.
This is what I got with Traxx:Input image, 8-bit 256 colour BMPOutput texture
I can see no logical reason for this to happen, and it just skews the image enough for it to not align on the model.
Thanks for the FlyRawGui link though Cale, I wasn't expecting it to work on 64-bit Vista but it did.
I just finished the model attempt. There is one corner it looks bad from, but it should be fairly easy to place that corner away from the track, assuming you won't see the tree from behind (i.e. if two roads close together, trees between them.)
That's a very interesting way of working around this problem, I had no idea MTM2 handled transparency like that. Can always count on you guys to have a clever solution for everything!
What I'm trying to do with this track is simulate a mountain-side road. I'm using various textures to give it contrast and such but with MTM2's limited draw distance I need some scenery to fill up space in a convincing way. The track is nearly 4 minutes long though, so 512 models wouldn't be nearly enough. I've worked out I have about 400 models left for foliage, which never seemed enough on short tracks, let alone a rally. I think with these alternative methods you've suggested I should be fine though. Thanks for all your help.
I UVmapped the model and it's ready to resize and retexture as you please. Let me know if you'd like me to e-mail it to you.
That'd be great, thanks. Hopefully this track will see the light of day and your work will get some exposure.
