Black artifact appearing randomly.

[sbeckley]

Hi,

Has anyone had what appears to be a reflection show up randomly? Both me a a coworker are having this problem. I have changed the texture in SketchUp and that doesn't help either. I have checked the geometry to see if there are two faces occupying the same space and that is not the case either.

Thanks for the help!!

The shading normals along the edge are parallel to the surface, which causes the shading to be wrong. We are going to add an option to KeyShot 4 to fix bad normals like this, but for now I recommend seeing if you can fix the normals inside SketchUp or perhaps export another format, where the normals are correct.
