I'm trying to fade out an object by using a transparency BSDF. With Transparency set to 0 it looks like:
When turning the transparency up to 100% to get the structure opaque I get this result:
I have no idea where those dark areas are coming from. The mesh I'm using has been imported from an obj file and was originaly created with a CAD software. I have tried to recalculate surfaces and removed all doubles, but I'm still getting those dark areas.
As I want to use it in an animation I think I could turn up transparency and just before it should go 100% transparent I'd set a keyframe on Restrict Rendering in Object Explorer, but I think it still might look a bit "harsh".
Does anyone has an idea, what could be wrong?
