VRayRT camera exposure having zero effect

[Art48]

Hi,

Is this an RT problem?
I got a VRayPhysicalCamera with normal parameters (exposure ticked) but chaning shutter value or anything relating to exposure has ZERO effect on the image.
WHen I use the production renderer it works as expected.

Is this a know issue?

I also made a new camera and copy pasted paramaeters, still zero effect.

It's been like this for me for a long time

Have you tried to turn off "Sub-pixel mapping"?

cha-ching. Why on earth is this a thing??

It seems that if RT is started while sup-pixel mapping is turned on, then no luck with exposure, but if RT is started with SPM turned OFF, then you can change exposure, turn SPM back on and still change exposure... odd.

This sounds like a bug. Which version of V-Ray do you use, also V-Ray RT/CPU or GPU?

[Pixelcon]

Im using CPU with an older nightly myself so it may have been fixed. My version is 3.20.01

This is fixed looong time ago, try with a newer version

Actually it should be fine in 3.20.01, so it could be something else...
