    Can anyone tell me, does LightmapSize affect bake quality, and if not, why would you change it?

    What do you mean by "Quality"?

    Lack of artifacts, sharpness, etc.

    Lightmap size will influence the appearance of fine details. Sharp shadow edges would appear blurry on a small lightmap.
    Direct and indirect samples will influence the amount of noise on a lightmap. More samples = less noise = longer bake times.

    Thanks. Coming from a film background is 'noise' similar to digital noise in an underexposed image or something else entirely?
