I cant figure this out. When i render in windows it’s all good, but when in ubuntu linux, i get these strange things. Anyone knows why? I really need help . DAm yafray …

Looks like the clamp RGB bug happening with gcc 3.4 and later, has been fixed long ago though. You really should update YafRay…

I’ve yafray 0.0.8-2, the best i can find in the ubuntu repositories. And it worked fine… Now it’s crappy. In recent and previous versions of blender. It just doenst give me the same render in windows then in linux. Obviously this happens because yafray is diferent, but this much randomness?? i dont get it . The cornell box doenst look like this when i render it .
