@Shadestrike: Hmm...I really don't know what the problem could be. As long as all the images and the MATERIAL file labeled 'Gem' are in the 'My_Objects' folder, they should work just fine. Get your flourite crystal on the 'Object Maker'. Be sure you click on it to select it. Then in the 'Material' box, type in RubyGem exactly as I typed it <capital R and G > and it should work just fine, the flouritie crystal will turn red. It will be the same for all the others as well.
Does it say 'material not found?' if so, then you are missing the material file. If not and the object comes up with yellow and black stripes, then your missing the image file.
