Renders now REALLY dark and I can't find the reason.

I haven't touched any Vray settings in my scene since last rendering and it was all working out fine. I was going to do an RT preview, and then MODO/Vray crashed while building the scene into the embree tree.

Now everything is rendering with some horribly low gamma or weird lut applied. It's about 4x darker than it should be. If up up the exposure by about 3.9 it looks almost right. Vray on top in image, Modo render on bottom.

Thoughts on where to look? AFAIK, none of the exposure controls etc. are on, and everything else is the same as before this went wrong.



****EDIT...great now something is truly messed with Vray. I went back to an older scene- was rendering fine. Add a new environment, fire up HDRLS- things then go dark. OK, fine...so I delete that environment...nope now EVERYTHING is dark to vray- all environments etc. that were working just seconds before. Guess I'll reinstall Vray?

Update- Somehow a vray physical camera was added to this camera. I have no idea how as I've never even gone to add/remove a package from this scene with Vray. This new scene is based on a old scene from a year ago, before I had Vray, and all the cameras were created then. Very strange.

If you can reproduce the crash, can you send me the scene ?

Is it possible that this preference is enabled:



If this is checked, starting any V-Ray render will add a V-Ray Physical Camera to your Render camera, it is explained in the tool-tip.

Thanks for the reply Vladimir!

That setting isn't enabled for physical cameras, and the camera in question was created a over a year ago before I had Vray, so unfortunately that's not the culprit.

The crash was quite random to be honest. I just hit "play" on RT and while the embree tree was doing it's thing and loading the crash happened. I've probably done that 100 times with this scene and that was the first it's happened.

So no need to follow up unless it happens again and I can track something down.
