Vray HDRI Dome Lighting Issue

Three65

Hello everyone,
      I am having a issue with my Vray HDRI Dome LIght casting a blue tint onto my model (see photo). I have been reading all day on how to try and figure this out so I can the lighting to match the HDRI lighting. So far I have tried changing the white point in the camera, basically all the settings and nothing seems to change. Also could it be the HDRI is just casting too much blue into the scene? I have also included the settings I have currently for this project that can hopefully help someone point out what my problem is.

Hi!
Try to lower the inverse gamma in the VRayHDRI parameters

Tried that all it does is lighten the whole scene up, the blue tint/cast is still in the render.

It looks like just after sunset (dusk) in your HDRI, so it's acting as it should with most of the light coming from the very blue atmosphere. You can custom white balance and then pick something that should be grey from that rendered image, and it will balance that as white, but the HDRI is working as intended.

You should get something more like this. (white balanced in PS)

Hey Scruples, thanks for the reply. Actually the HDRI is more like set at Noon, its a bright sunny day.

Here is the HDRI I bought and am using on this project.

Ewwrrr, ok then it looks like Vray isn't treating your HDRI as an HDRI at all. I might scrap setting it up as a dome light and set the HDRI as a dome into the environment because going through your settings I don't see anything explicitly wrong.

I was starting to think maybe there was a bug of some kind myself, perhaps ill rebuild the scene and see if that changes anything. Thanks for the insight and your time.

Run your HDRI through a color correction node, and you can control the hue there.

Or you can edit your HDRi in photoshop. You gotta have in 16bit mode though

Actually, I checked your white balance in your settings. Go to manual and try to add blue to it. Try 7500.
Edit: Simple rule for white balance. If its blue add blue. If its red add red. Just switch it to custom and below 5000ish it becomes more red, which means it cancels out red, and above 5000ish it is blue, which means it cancels out blue.

Hey Kurtr, I actually did try running the HDRI through a color correction node. But it didn't seem like it had any effect either, also I tried changing changing the white balance both through custom and temp like you suggested and it didn't really seem to effect it either. (See photo) Its so strange, makes me wonder if the file is bugged.

Kroma!

You don't have anything in the Environment settings do you?

Hey Kroma, nope nothing in the Environment,

Hey Have you tried rendering without the camera, through perspective, and compare?

Three65

Ya it renders the same in all the viewports

Next thing to do would be to turn on a global material override, and choose the default grey V-ray material. See how this renders.
Then if it's still blue, you can turn on some render elements, such as Global Illumination and a Light Select for the HDRI or any other lights you've got.

Thanks for all your help everyone, I just ended up starting the scene over and everything seems to be rendering fine. I am not sure what happened in the starting file still, I feel like it was a bug of some kind. Cause I tried for several hours everything I could think of along with advice from you guys and some other vray forums.
