I’m having a problem with Cycles and OpenCL rendering.
Whenever I render with the GPU, the world color gets in the way and I can’t see anything else.
Windows 10 Pro 64 bit
AMD Radeon R9 270X (driver 18.104.22.168)
Blender 2.77 Steam version
Everything was working fine yesterday, then Blender got entirely black (the entire window), then the render doesn’t work anymore.
