Light Cache problem

thanks guys, I didn't notice I've had the LC on primary...

Yeah, I would also suggest, simply swap LC for secondary. I did LC for primary once, and it looked the same as your render. cheers

Although in the wrong forum, try setting the primary bounces to Irradiance Map with Medium settings and set secondary to light cache... 1500 samples, sample size as it is originally... should work fine

Hi, Did you use Light Cache for primary or secondary bounce? ++

What about your anti-aliasing settings? Is sub-pixel mapping" + "clamp output" on?

Sorry, My bad, wrong forum
