Discrepency between Beauty and Light Mix

[dj_buckley]

I've just setup light mix.  The scene only has 3 lights.  I've not adjusted any setttings yet in lightmix, just separated out the lights.  But there is a difference between the beauty pass and the light mix pass.  The shadows are lighter in the lightmix pass.  I'm just waiting for the render to finish and will upload comparision shots when it's done, but just wondered if anyone had experienced the same thing.

But if my settings are as shown in the screenshot and those are the only 3 lights in the scene then it should look identical to the beauty right?

it should be unless you have anything in the rest that you dont know.

[dj_buckley]

there are other lights in the scene but everything is turned off.  I turned 'Rest' off anyway just incase it was picking up any of the other lights that were turned off.

Open these two on top of each other in PS and switch between the layers.  They're not identical and they should be.

Corona and DCC version?

I always found this to be the case as well, although very minor, so I never really even bothered to do PS overlay to check. I thought it's byproduct of some order-of-operation or layering method, etc..

Yeh it's more obvious when you view the whole image, but I think even that crop is signifcant enough.  If its perceptible just from switching from Light Mix to Beauty in the frame buffer then it needs fixing imo

Corona and DCC version?

Corona 11 Hotfix 1 - not sure what you mean by DCC

[Avi]

Hey, can you try with Corona 11 HF 2, just to be sure? because there were some changes related to color and removal of gamma operator.

Hi Avi, no luck I'm afraid.  The issue persists with HF2

I will look into the issue.

[dj_buckley]

Will do.  I've also got a another issue/bug with this scene.  Can I report it in the same ticket?

DCC is Digital Content Creation or in this case Creator - ie, 3ds Max or C4D with associated version number :)
