Post: RE: Fractal Etch mapping

There is a bit more to the Fractal Etch scheme than making the 256x256 cube maps. 256x256 is OK for rendering the planet for a representative image, but what if you look closer? The image can get ver...

Post: RE: Fractal Etch mapping

Inside the program the maps are 6 x 256x256, so they perfect. That is just a screen grab (and it might have a little gimp processing done on it), so the edge pixels may not be perfect. Using the cube ...
