GPU rendering no light penetration in large scene When i am rendering in cycles large scene (not really, 470k verts) in GPU mode there is no light penetration through holes and glass, even if i render with 10 samples. In small scene (&lt;80k verts) all is ok. In CPU rendering also all is ok, but it's not funny when you render one frame for 2 hours.
Radeon 7970 (OpenCL).
Is there any solution for this problem ?
check the progressive refine box in render panel.
