I rendered a model for a friend today, and for some reason, the toes of the creature he wanted me to render (called Gene, a made up creature called a Chim, shown above) turned pink. He said that the same thing happened when he tryed to render it. I decided to investigate, since I have had similar really bizzare problems before when rendering. Here is the deal. In Sketchup, it is possible to color two sides of a plane (or face) (with no thickness) two seperate colors. In more "Advanced" (complicated) programs, such as Blender, you will find that impossible. If you texture a face grey, both sides of it are grey, or one side is grey and the other is clear. Now certain rendering programs, such as Kerkythea, are designed to work with both Blender and Sketchup, so there is a bit of a comprimise. Basically, the inside of Gene's toes were painted pink in Sketchup. Kerkythea seems to pick the color that appears on one side of the face and paint both sides with the same color. This seems to be totally random. I painted the inside of the toes the same color as the outside, and they came up as grey this time. The ears however, are supposed to be black and grey on the back, but Kerkythea made them pink. Basically, if you use Kerkythea, paint all the faces on your model so they are the same color front and back.
