Hello,

I found a life module 3D model for UCSO, imported it in Blender 2.79, modified it, and exported it with Vlad's tool.

The problem is that the module becomes transparent when you enter it or look from below.

Lots of (most of) vessels do this. The content creator has to create an interior for the vessel and have a texture for it. The mesh and texture wizard jedi ninjas here on the forum know various ways of creating interiors, but that's they only way I can do it.

I hear tell that there's a way to texture both sides of an object, but I don't know that trick.

Thanks for your help. I solved it by using the 'Solidify' modifier. It appears correctly now.

Faces of meshes only face one way, which is defined by their normal. if viewed from the other side, they will not render. This is a general concept of 3d graphics processing, entirely unrelated to orbiter.

This^^^^.
Blender can show this "effect" by selecting the option "Backface Culling" (press key "N" and scroll down to "Shading").
