A primer on how to get textures on a torus based on a primer from and his and of course 's I used hextgridIFS for Fo2 and I know a few others work too but, not sure about all! Copy and paste the parameters from my [link] and tweak from there! Hope this helps a little!
Addendum Not all the settings (position, rotation, formula settings) work on all dIFS formulas! This is merely a primer as to how I got from point A to Z on [link]! If you "Start from scratch" expect to play with the above settings to get round Tori! I also suggest to leave the formula settings on the TortoricalIFS at their default for now!
