Hi, I’m using blender 3.3.1 at the time of following this course, and I’ve noticed some changes in the baking section.
TL;DR;

Long Version
Now, instead of Ray Distance, we have a Max Ray Distance and an extrude fields, along with a cage tick box. According to the blender docs, it is preferred to use a cage for complex objects with seams. Basically, the box can be automatically calculated with the cage extrusion field, or you can use a custom object as a cage. Using the cage extrusion field is just fine. Just check the cage option and use the extrusion instead of the max ray distance.
Hope that helps!
