oh, you mentioned some I haven't found yet, thanks! I found a plugin for IFS for PovLab (a flavour of PovRay) by now too, and what I saw done with it looks VERY cool, but I haven't tried it yet. (has anyone else?) I realise now that UltraFractal and Xenodream have no export capabilities for meshes. (though Xenodream says they will add it in a future version) I'm using FractalExplorer quite a lot now and I'm enjoying it. I have discovered that it can generate obj terrains from fractals but it coughs out when I set the size too high. :(
