Can you show the baked lightmap scene debug view as well?

[next stone]

It looks like a piece of geometry there

Possibly hidden in the editor but visible to the lightmapper as I suggested

It may also be inverted rather than hidden

so how do i delete it?

First you figure out where it's from

Is it a separate object or a part of the blue mesh

Can you click to select it? Can you move the camera inside it and view it from inside out?

[rain bough]

ima try making everything invisible except the blue mesh

[next stone]

I'd select and move the blue mesh to see if the phantom geometry moves with it

[rain bough]

yep still there

so its apart of the blue mesh?

[next stone]

Seems like it

i kinda found a way to fix it

i moved the vertices a tiny bit in probuilder
