So I work with a partner who’s still using version 5 while I’m using 7 and we noticed that working between versions, when we render (both using VRay) for some reason everything takes on an orangish tint whether working with default Rhino materials or VRay mats. Thoughts? Also when I open her versions in v7 (though this also happens when I open my old versions from 5 and 6), render view exhibits a hugh black artefact in the horizon that takes up a large part of a hemisphere.
