What solutions have you thought of so far?
I have tried changing the technology, the shadow softness, and diffuse scale
After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
Some parts look like they have a different color but that’s because when CastShadow is turned off, the sun beam goes the wall. So the colors will change depending on the camera angle but it’s not a big deal.
You also have wayyyyy too many parts. So I’ve gone ahead and made it for you on Blender, way more optimized;
Even made sure to include the gap for the window/control room.
Import it by going to
AVATAR > Import 3D > Select the file > turn on Anchored in the import settings
And after importing, ungroup the model, cause really it’s just one part, and SELECT THE MESH AND INSIDE OF ITS PROPERTIES, TURN ON DoubleSided So it doesn’t look invisible from the inside.
Hope I solved your issue, if you have anymore concerns just reply to me!
