Hi all!
I model old Turkish-made aircraft for fun.
Nowadays I'm modeling an old flying-wing sailplane design, with an intent to import it to Outerra and make it flyable. I'd been going well for my standards, but today I ran into a problem that is driving me insane
There are weird shaped shadows on the inner sides of the two vertical-fins, although the outer sides are perfect (again, for my standards).
Here, you can see the shading on the inner side:
Here is the normal, outer side:
And this is a screenshot from blender render-view:
I can't really say that this is an Outerra-related problem, because I'm not a pro in modeling so I may well have made some modeling mistakes. The fin profile is NACA 4306, a somewhat complex profile to model for a hobbyist like me. However, having seen that the outer side renders fine in both Outerra and Blender, and having been unable to solve the problem no matter what I did, I felt that I should resort to the forum.
I'm using an AMD system with an HD7900 series GPU.
Thank you in advance.
