Lightmap Baking Help - Blotchy

Hi, any ideas on what setting I need to modify to get a clean bake? I’m just using a plane, a sphere and two cubes re-sized. I tried to modify all the settings and they’re giving me similar results.

Thanks.

Try turning of “Compress Lightmaps”, compression can cause this type of Artefakts.

I’ll give it a try later tonight, thanks.
