Fixes #90524

The lightmapper used to index into incorrect framebuffers during seam blending, which caused artifacts to appear on lightmaps.

Nice catch. I haven't tested the modification myself but the change makes plenty of sense.

Do you guys take cherry-pick PRs? I think this one should also be added to stable branches, considering how small the code change is.

The PR already has a cherrypick label, and it should be cherry-pickable without any conflicts already. Therefore, I don't think it's worth opening a dedicated 4.2 PR.

It makes sense to open a dedicated PR when there are conflicts when cherry-picking the commit, but for small code changes (less than 20 lines), this is pretty uncommon between the master and 4.2 branch.
