Just guessing: inverted normals

I built a simple closed shape, a kind of up-down stroke on top, and a convex bottom, then extruded it. the result is a sort of cylinder with concave dent on the side. I’m not sure yet, having not imported it into blender, but in Codea, the faces in the indented part don’t appear. I suspect they are present but their normals are inverted (because that part is concave?).

If this is a known thing, please comment. If not, I can explore further or provide pictures or whatever would help.

@RonJeffries,

This might be a known issue, but we might prioritize it so it won’t occur in the future. Can you please send the .UMK file to “hello@umake.xyz” and we will take a look to understand if it is the same bug we’re ware of.

Thanks,
Evi

will do, next time i’m on the iPad.

Thank you!
