Hi all,
We've moved to corona v7 in the office and I think we've just found a bug.
On our scene we are using two Corona Sky objects, with two different HDRi's. One Corona Sky object is set up just for only GI (so Visible directyly, reflections and refractions are turned off) and the other one is set up the other way around (only Visible by GI is marked). This way the scene is lit by one HDRi but the visible sky and reflections come from a different HDRi.
The thing is that, when we do this, a lot of fireflies appear on the scene, specially around very glossy objects, making the image useless for production.
I've been trying different setups with very simple scenes, and this bug appears to happen everytime you use a Corona Sky with and HDR with "Visible by GI" toggled off. I mean you don't even need the second Corona Sky for GI. What is mandatory is the use of an HDR, it doesn't happen with Physical Sky and Simple Color types.
We are using Corona 7 hotfix 2. This bug didn't happen with Corona 6.
Thanks,
Julio
