Blend material giving odd coloured reflections.

Getting blue/green where I’m expecting red or just grey. Is this a known bug with blend material or am I doing something stupid? :smiley:

Simplified scene here.

Thanks

It’s a known bug, already reported on Mantis. Blend+bump+uhd cache = this.
Solution: use PT+PT (which may be generally good idea here as it looks like exterior scene) or simplify the material (use no blend)

Great. Thanks for the solution and tips!
