I've created a scene of medium complexity in 3ds max and am using a few standard spotlights. Also using Vray renderer. The problem is that if I select Vray shadows (or any other type of shadows) for the spotlight, the light doesn't render. It renders fine when shadow options are off.
Not sure what the problem is. I haven't used many spotlights with Vray before. I tested with just one spotlight and same problem. I've also got a regular Vray light in the scene which is rendering shadows just fine.
