I have a scene that was working fine, that now isn't. I'm pretty sure I didn't change anything as far as the Kray settings, basically using the settings from the Pro. Viz. scene, with tweaking the lights. But I've changed the scene a bit

I've attached before and after. Thanks in advanced.

P.s. I gives the splotches on the renders with or with out the carpet texture applied.

My guess would be, that the OB8 has the KrayPhotonnumberMultiplier shader / motion modifier that you have to use in every ligh to balance the photons between interior lights...

Check that, if you rendered this before with OB7...

Thanks Peidian. I know I didn't render this before OB8, and I'm pretty sure I have the multiplier on all the lights because I'm sure I did it to the original, and then they where cloned. Both images (the before & after) have the same set up.

My guess - bad saved gi file?

I got it fixed. Basically need to fix the Sun light. It was Inverse ^2 but only 100 m and no Sunspot applied. It got way more photons in there and fixed it right up.
