I apologize if this issue was already posted but I wasn’t able to find a similar problem. I am trying to bake this floating object on the box as illustrated on the bottom left viewport.

@Maco , there is a new patch to “Selected to Active” baking option in the alpha version of Blender 2.9. This setting “limits how far rays can travel before they are excluded from the baking result. Useful for meshes with holes in them.” https://wiki.blender.org/wiki/Reference/Release_Notes/2.90/Mor…

Normal baking - one object is baked out on two opposite faces
