Arnold Render Preview is significantly brighter than the final render.

[Anonymous]

I am trying to light and render an interior scene in Maya 2018 with Arnold 5, but when I render the scene using "Render current frame", it is significantly darker than what shows up in the live Arnold renderview. Both are set to render in an sRGB colorspace. It's almost as if the final render is completely ignoring indirect illumination. Why is this the case?

Hi!

You have 2 gamma corrections for your preview.

1. View Transform "sRGB gamma"

+

2. an additional Gamma correction of 2.2 for preview

That's one too much.

To match preview with final rendering either set Gamma in Preview to "1" or correct your image after rendering with an additional gamma value of "2.2".
