Function GIProbe.bias
Offsets the lookup of the light contribution from the GIProbe. This can be used to avoid self-shadowing, but may introduce light leaking at higher values. This and normalBias should be played around with to minimize self-shadowing and light leaking.
Note: bias should usually be above 1.0 as that is the size of the voxels.
