VRayLightSelect and PDPlayer Image Discrepancy

[jujubee]

Perhaps this is beyond the scope of VRay itself.
I use baked-in LWF which may be the issue. I'm asking to see if anyone has encountered this problem.

When I follow the VRayLightSelect Youtube video here, I get different results between the original image and the image I'm trying to adjust.

Here's my image. It has two Vray Lights and a Sun. There's nothing fancy about my Vray Materials.
You can see the one on the left is the "correct" result (minus the sky) and what would typically be seen in the VFB. The one on the right is what happens when I put all the layers to "add" which makes it substantially brighter. As a result, there's some banding occurring from where the sun hits the ground plane.



How do I get them to look the same, or what am I doing wrong?

From the timeline it looks as if you are mixing many different element types. With Lightselects you should group lights. Every Light must be in there once, no light must be in there twice. then you add up ONLY the light select elements. This is what should match the RGB. If you add any other elements (like reflection, illumination or any other) then you are doubling things up and hence causing things to go brighter.

Three different lightselects to control them all independently.

1) Sun
2) Interior left light
3) Interior right light

You CAN choose to group them up together if you want to, but I followed the video and wanted to control them all on their own layers.
