Irradiance is interpolated between final gather points. Since each of your
tiled renders does not know about the final gather points in the other renders,
there will be incorrect interpolation at the edges. Try rendering each image a
bit larger than necessary, then blend the edges when you composite the tiles.

Subject: Large FG image rendering problem
I am trying to render images in the 6000x6000 pixel and up range. I'm getting
memory issues around 5kx5k so I started rendering subregions and tiling them
together. The problem is, once I put them together, there is a subtle but
noticeable color shift at the seams. I'm assuming it's due to a FGmap issue. I
've tried "append", and "generate" on the FGmap usage. Does anyone know how to
work around this, or another way to render huge FG images?
