Vray Physical camera, render elements black (exposure issue?)

[dre4mer]

Hi guys,

Bit of an urgent request for help here, I feel like i'm missing something here and that this is an exposure issue, but diffuse renders black, so do the lighting passes when using a physical camera. RGB pass looks fine, if I bring the diffuse pass into after effects and put exposure up like 100 it's still black. Like there is no data in it at all.

Passes all work fine if I don't use a vray physical, so it has to be a setting on there but I've been messing with exposure settings and nothing seems to help, I have my scene all lit and built so I can't just suddenly change all the lighting to accomidate this. Anyone know what i'm doing wrong?

Thanks for any assistance!

Actually, if I plop a normal camera into the scene it does the same thing! So it isn't just a physical camera setting. VERY odd, because the diffuse pass works fine with either camera in a fresh scene.. seems like I managed to somehow break passes in my main scene they are super dark. The raw lighting pass does have some data in it if I brighten it alot it starts to show up , but diffuse is black as black can be and nothing ever appears.

After further experimentation it sort of seems like maybe there is just literally no diffuse lighting in this model, it is metallic in nature but it's really hard to believe there would be absolutely zero diffuse. Which is why it seems like something isn't working right or I have a setting wrong.

Hey, we missed this thread somehow. Do you have an example you can share?

Check your shader -- it probably has zero diffuse contribution.
