I am *sure* I’ve seen this before, but can’t find how to get rid of it. I have a few max spotlights (with vray shadows), a vraysun (turned off as I only want it to control the skylight strength/colour).
What else should I be looking for?
Well, it seems I have solved the problem. You need to check ‘invisible’ on the vraysun, even though it is turned off!
Yep, because the sun disk is actually a part of the sky (which reads the invisible option from the sun).
Best regards,

I see. Didn’t realise that. I assumed the sun is just the sun, and the sky is just the sky.

hah. I wasn’t being sarcy, though reading my post it could be perceived that way!
