Yes, depth is a problem....in the case of the cubes, I needed to show alot of them on screen, hence the 8 polys and 512 textures....in one scene of infinity there are over a dozen on screen, and you have to escape them. That is why I made them flat cubes and tried to put the depth in the textures.
As to the green cube, it is the beginning of the early TNG cube....I still have to add the yellow branches to it, sofar I am not happy with the many attempts at doing so.
Thanks for the comments and kudos...the reason I can do so many models is that the meshes have been ready for quite some time, just had noone to texture them...now that I can texture, I can finish them up myself. You should see anywhere from 20 to 30 models from me by years end.
