Mcronin Posted February 26, 2003 Share Posted February 26, 2003 SESI used to have a page from their old site about the RAT texture format, but it has since fallen into the bit bucket. I want to use RAT textures, but can't can't find any clear answers in the help docs about actually creating and using them. They're supposed to be a type of block ordered, mip mapped texture, I thought. However, using iconvert or iview to save, say, a tga out as RAT and then using the RAT in my scene doesn't seem to be giving me the right results. For instance, if I use a simple black and white grid, save it as RAT, and use it on a ground plane in my scene, the grid deteriorates horribly as it get's further from the camera. Can anyone tell me if there are any special considerations for creating RAT textures? Should they be square powers of 2? Is it just as simple as using iconvert to convert from any format to RAT, or is there more to it? Quote Link to comment Share on other sites More sharing options...

Mcronin Posted February 27, 2003 Author Share Posted February 27, 2003 This page is full of a lot of good info. It's a shame SESI removed it from the site. Maybe it should be added to the tutorials section here if SESI will allow it... Just a thought. Quote Link to comment Share on other sites More sharing options...
Stremik Posted February 27, 2003 Share Posted February 27, 2003 So. Does anyone know if RAT files can be used for Bump/Shadow mapping or it is still not recommended? Quote Link to comment Share on other sites More sharing options...
