I'm new to Vray after switching from Maxwell. Just to get used to the UI, I set up a few scenes in a model and tried to render them. The first scene(interior) turned out fine. As far as I know, I didn't change any settings when attempting to render the next scene. I have GI checked with CIE Clear set and Global Illumination turned on. As you can see, the sky is purple, green, and yellow and the noise is purple. I've tried different sky models and nothing changes.
Any idea what could be causing this?
Obviously, photorealism isn't being attempted in either of these scenes. I'm simply trying to figure out what happened with the sky.
