Something strange is going on. I render on my machine and it looks fine, however, when someone else renders it out on their machine, it’s dark. I converted the scene to a Corona scene, and it rendered dark, like when it was rendered on the other person’s machine. MAX gamma is 2.2 and so is V-Ray and the VFB. This is an interior scene with an HDRI in a V-Ray dome.
Check their “fileoutgamma” in the maxscript listener - it’s not set by the max gamma value rather stupidly.
sRGB button disabled in vfb?
it’s being saved from the VFB as an EXR.
it is enabled in the VFB

It sounds like maybe it’s not seeing the maps. You might try to update the hdri link in the map/material instead of the asset tracker.
It was a color mapping thing.
