As the title.

EDIT: I think this just happens in certain situations. I’ll try to narrow it down when I deliver this project.

Looks like a simple (hidden) mesh light will not render when the usage of Hidden lights is disabled ( **V-Ray \> Global Switches \> Hidden**  **lights** ) - please do provide more details about when is this occurring, thanks.

It happens if you create a mesh light, start IPR, then hide the light. Refreshing the IPR does nothing here, although stopping it and restarting it clears it.  
So it’s fine really, although interestingly this only happens with mesh lights.

Thanks for clarifying. It appears that if Hidden lights are disabled **during** IPR, it will not update when actually hiding the lights, however, if disabled **prior** starting IPR, then it should have no issues. We’ve logged this in our bug tracking system (internal ID number: VMAX-10340) for further investigation.
