I have an issue when trying to use a model of mine and light it in the Unreal engine. It states that the lightmap UVWs are overlapping by a small amount - 1.1%. This number has bounced around depending how I manipulate the UVW, from 1.1% to 98% when I try to relax it. Below is my UVW map with overlap highlighted in red - doesn’t look like 1.1% to me.

This is causing lighting defects for me in the engine. Or, at least I believe this is the problem, as messing around with the UVWs is changing my problem in-engine.
This is what the problem used to be. Note that the light source is where the Move gizmo is (at this point, overlap is said to be at around 8-9%).
This is my problem now that I have shrunk down the UVW to fit within the 3ds Max checker box:
Still problematic, but a little better (1.1% overlap… apparently).
So how do I fix this issue? There’s no way I can manually remove overlap for all of the UVW - that would be a nightmare. Anyone have any recommendations?

Thanks in advance y’all, I’m really stuck here.
