Vray RT Exposure vs Production Renderer Exposure

[m4rtyn]

Hi all

I have an issue with my exposure settings using Vray RT vs Vray Production renderer. Does RT use exposure in a different way or something? In RT my progressive images show lighting and HDRIs working well, but in production mode, the image goes dark and underexposed, yet all Ive done is switched over and made sure GI (BF/LC) is on?

What am I missing?

Thanks

Hello,

Are you using the bucket image sampler when rendering with V-Ray Adv renderer? One known difference between the bucket and progressive (both Adv and RT) is the "Affect background" option in the Color Mapping section. It only works for the bucket image sampler.

Best regards,
Yavor
