I have a strange problem with Yafray: it crash only when I call a render with global illuminationset , on my windows platform. Not matter what I render, it happen (even with the default scene with the single box). Has anybody faced a similar problem ?
Full GI set on medium quality often screws up with me.
If that is the case with yourself try boosting the quality to highest and it seems to run ok.
I think it’s linked to no photons in the scene but I may be talking out of my ass there.
