You'll have a slight problem with 3DS Max generated texture coord's even if you can get them out. The problem will come due to Max using repeating textures for it's models (which aren't supported in the yaroze libs). So, you'll get texture coords such as t=1.1, u=0.23 (1.1*texture_width, 0.23*texture_height), which is off the right hand side of the first copy of the texture, into the second copy of the texture. You cann't really get round this easily...... Texture information is exported in the ASE file generated by Max v2 and upwards, so you should just upgrade to the new version (I never found out why Max's 3DS file generation omits texture coords, pretty shit really). As I said earlier, you'll still get a few problems though.....you may find that you have to repeat part's of your texture in the cache to allow Max texturing to work correctly, and that'll take up more space in the cache, and slow down the display as well (more texture cache misses). > OK, make that three quick points.

You could try to contact Malachy (the guy who wrote RSDTool for Sony) - he was working for Shiny in the states last time I heard from him.... > Thanks once again, > > Tom Craig.
