VRayLightMtl - How can I render the intensity, the same as the original bitmap's?

[Morne]

Hi all

I'm trying to render a whole bunch of VRayLightMtl's with the same intensity, brighness, contrast etc as the original jpg file. In other words I want to put the render next to the bitmap, and it should look at least 95% the same. Can I somehow exclude it from GI or whatever?

I'm using LWF and use this technique for tv screens and also fro shopfronts. But currently it is coming out too washed out or too oeverexposed or just looses it's colour, very dull. The rest of the scene is fine, just the VRayLightMtl is coming out a bit "off". I'm tweaking the multiplier in the VRayLightMtl up and down, but not getting the result I desire.

Any help here please?

Have you tried the "Compensate camera exposure" option?
