Wow, I can't wait. I did the 3d Ecosystems tutorial today and decided to explore it more on my own by creating a sort of rockslide off of a mountain. So I got my "slide" down pretty good and then in the end I could not change the material of the rock. If I did try and change it it would either delete my cube(that the rocks are in), or texture the cube. Is there a way I can keep the the cube transparent and change the material on the rocks? I have tried adding layers, moving the layers, etc tec. can't seem to find the way.  If worst comes to worst i can make the "Chipped" material work but it really dosent show up well enough over the dry brown landscape it is supposed to be one.
