Could be related to "lightlinking" i didn't figure out yet.. In another file it works fine... I'm looking still..

[Zdravko]

Could you please send the scene to: vraymaya@chaosgroup.com

[olivervfx]

I can't send it , but it involves, having Velocity passes and combined with motionblur..

It will make the scene "darker" i'm looking as we speak , ...
So i can tell exactly what it is.

This seems related to the vraylightmtl / motion blur issue from last week.

If direct illum is turned on and you're, say, rendering the interior of an object moving very quickly, it can actually cast a good amount of the scene in pitch black. Turning off direct illum brings back the lighting info.

Basically, the exact shaders and situations that triggered that recent crash bug, this time specific to the direct illumination switch.
