problem with RPC people using Vray sun and Vray Physical Cam

[add101]

i'm having an issue with rpc elements rendering in a scene with vray sun, and vray physical camera. they render out black.
does anyone know what's causing this?

i've used 3d trees for the scene, but there are some rpc trees i really wanted to add into the mix as well.

Rpc's are self illuminated at 1 so they will come out dark when using exposure. I have not used them for years so I'm not sure if their output can be set higher you might try in the mass edit roll-out.

If the trees are in the background, maybe render them without exposure and comp them in?

also you should check exluded object's list in vraysun settings.
Somehow rpc'z are by default excluded from the sun, which
contributes to them rendering out dark.
Furthermore you can set their illumination to 0 (under rpc settings-
mass edit). That way the exposure will give correct results.
Hope it helps
