Title: Corona AO produces Light Leak Like CRAZY!!
Post by: banijamali on 2017-04-08, 13:09:49
Hey everyone.
Thank you Corona team for this great rendering engine.
Although we encounter problems using this renderer, (which all other renderers have too) but I like it the most.

Anyway I have faced a strange problem here. when I use Layered material and put a Corona AO in the Mask slot (I'm trying to create VRaydirt-like material), I get LOTS of light leaks in my scene. I can't believe the amount of the light leaking in from almost everywhere!!

PS. every surface is shelled and the only light source is CoronaSun+CoronaSky, got no glasses in my window and also have used Corona Portal.

PS. There are NOOO lights in the cabinet shells!!! it's just light leaking in!!!

Thanks in advance.

How can I get clearer AO in my scene generally?

Vhat Corona version you're using? If it's 1.5, it could be this issue: https://coronarenderer.freshdesk.com/support/solutions/articles/12000020539-i-can-see-splotches-spots-light-leaks-in-my-image-

try to convert materials in scene to corona, and check position of scene near 0 coordinates

You still need to reset render settings to fix internal UHD values.

Well nothing worked for this scene.

Finally I deleted all AO maps.
and also reducing high amounts of bump value in my main materials helped a little.

1.6 (latest RC or stable version released in a week) does not have the hidden parameter issues
