Hi everyone,

I am a complete newbie to CAD & 3D/Rendering, however I am having a grand time playing around with the trial version of Moi3D. Whereas with other programs it seems like a living hell making a basic shape, constructing with Moi3D is easy!

When I'm working with solids, everything is fairly easy. The construction may be incorrect, however since the planes are filled in I don't have any problems. Now I've been experimenting with transparency, and nested, or "shelled" designs. However, when I export these files as .3DS, and set the exterior layer to transparent, my interior solid is becoming transparent.

Some faces of the solid remain solid, while others are completely transparent as if missing the filled in plane, and some edges are semi-transparent. I can't figure out what is wrong with my file. Could someone take a look at it?

I'm fairly sure my interior object is solid, but why am I getting such weird reflection problems with the exterior shell?

Thank you kindly,
Misiu
