Standard Max lights in Vray

[Devin Johnston]

Is anyone aware of any problems using standard Max lights in an Vray animation? I've got a scene where I used standard lights and when I render out the animation 2/3 of the frames the lights don't cast any light at all. I'm using Brute force and LC, I don't think it's a GI problem.

I have had instances where I used Vray lights and then put in a few standard lights and it was like they were not working. Try increasing the value to like 10 times the value. Are you using a vray camera?

The only thing I know of with standard lights that could cause the issue is your shadow type, but I don't think it would affect the light casting illumination. Is your light being just ever so slightly being blocked by an object?

[Devin Johnston]

No it's more like what Jason said, it's like they aren't there at all and only occasionally do some of them show up. I'm removing them from the scene because I don't have time to debug this but they certainly don't work.

I fixed similar problem by making the geometries of scene included to the light properties (Exclude button) and set it to both for Shadows and Illumination. hope this fixes yours too
