I’m rendering an animation and I noticed that there’s a weird problem with the top rotors on this helicopter model.
I’ve double checked that my mesh isn’t overlapping with anything. I’ve already recalculated and flipped the normals. None of those things have worked. I’m using the Blender Internal renderer in Blender 2.71. How might I be able to fix this?
Sorry I can’t post my .blend file. It wouldn’t show up in Dropbox.
I made sure that there were no overlapping objects. However, I might have overlapping faces, like you said. If this really is the problem, how can I fix it?
Okay, so I tried to remove the doubles again with the merge distance turned up and the rotors now look a lot better. However, as you can see, there are still some black spots left and removing the doubles any more would take away too much of the detail. Any other ideas?
Those blades are a triangulated mess, and you have a bunch of vertices merging into one another. I fixed some of them by mostly getting rid of edges and rejoining vertices where they should be, but you’d be better off modeling new blades
This usually happens when importing something from another program, so it’s not your fault. It’s just up to you to either fix it manually, or make new blades. Blender’s Edge Split and other modifiers aren’t really going to help much here, and it’s not Blender’s fault either, it’s just really bad geometry.
Hmm…well, the model’s not mine. I suck at modeling and I think that doing it manually would take too long, so my hands are pretty much tied. I guess that the rotors with the doubles removed should serve my purposes pretty well. The motion blur in my scene will probably hide the errors anyway. Thanks for the help!
