My tk2dSprites are using the provided LitBlendVertexColor shader. When I place a point light in my scene that's using vertex lighting (rendering mode set to Not Important), I often get these hard lines (notice on the window)

I was just curious if there was anything that could be done about this, besides switching to per-pixel lighting?
Edit: Probably worth nothing those hard lines are were the tile map is partitioned. The light affects only one of the partitioned chunks.
