  • Strange Reflection artifact with GPU and bump map

    Ok so this is an odd one, but i noticed a strange line in my reflection pass. Seems to be coming from the bump, and maybe even the bump texture itself, because if i replace the texture with a procedural noise instead, it dissappears. But i thought i would send the scene etc.

    In image you can see the black curved line, this is in the reflection pass, and seems to be connected somehow to bump map of the wall material (all the walls, ceilings etc share this material) As you can see the bump isnt noticable on walls itself. If i delete the bump it disappears, and if i render with CPU it dissappears.

    Scene attached.

    Oddly enough, it doesn't appear on my end. Is that a stable build? Could you try the latest official?
