Model turns inside out when transferred to Tennogen. How to fix?

Question

3D

Modeling a sword in Blender. I make various objects (base, handle, blade). I create the base itself by simple extrusion, and after a few Boolean operations I cut out the necessary places. But when translated into the Tennogen program, in order to view the model, the base of the sword is translucent on the sides. How to fix this?

Answer 1

With normals you are completely seams. No two-way normals will help you. There is an opinion that after boolean operations it is necessary to recalculate the normals: Shading/UVs ‣ Shading ‣ Normals: Recalculate
