Hello George, my colleague Alejandro asked you for the scene but since you open two at the same time I think that he replied to the other one.
We are still trying to figure why it happens you your scene, and how to make a workaround for that, notice that it has nothing to do with Layama itself, if you place a cubic V-Ray 5 Camera on your scene it renders wrong, even without any Layama intervention.
Also if you try to make a new layama project in a scene made from scratch with V-Ray 5 it works perfectly so there is something in your scene what we didn't identify yet that is "breaking" V-Ray 5, once we find it we'll try to make a workaround and also we'll get in contact with ChaosGroup to solve it.
Regards, Víctor.
