C4DtoA Light bug

Hello there, im working on a scene with c4dtoA v1.5.1

I got a ship that i need to lit, i have now 174 lights, mostyl point lighrs and 4 quads.
And it renders fine, the problem is if i'll only add one more light (doesn't matter what kind, point, quad, spot etc.) picture renders without any light, just some dark model.

And if i'll update to arnold v5 from my current version, will i lost my lights?

Unfortunately i can't provide scene file.

Can anyone help me?

1.5.1? That's pretty old. Updating won't destroy the lights, but there's lots of other changes that may make your scene render differently.

How about exporting your lights to an ass file so we can test it?

Or posting an Arnold log for a problem render?

Yeah, I would be curious if the problem is still there in a newer version.

Do you have any light linking in the scene (Include / Exclude lights per object)?

Also it would be interesting to know if setting Low light threshold to 0 solves the problem or not. The render might be slow with this setting.

Yeah thanks, i had disk light(moon) set to only affect the ocean. Now it's working fine. As i don't have any advance shaders now, would it be good to update to a5? I only care about the lights

If it's just the lights I guess it would be safe to update. You can install back the old version if the render has issues.
