Can I use RoomBox with Chaos Vantage?

Yes, but with some limitations: you need to disable sprites.

As of today, emissive material support in Vantage is limited. Transparency is not supported, so sprites are rendered mostly black. "Compensate EV" is not supported either.

Therefor, you need to follow these steps:

1. In the RoomBox editor, disable all the sprites

2. In the V-Ray material editor, edit the RoomBox emissive materials:

   1. Disable "Compensate EV"

   2. Increase the Intensity until you can correctly see the room in your render (the exact value depends on the lighting conditions in your scene
