Thanks a lot, @FedPete ! I found the solution messing with the cage and cage extrusion in blender 3.3. To others having the same issue, if I understand the blender docs correctly, for complex meshes with seams, etc, it is recommended to use a cage and use extrusion instead of ray distance, or a cage object, for the ray casting.
I just ticked the cage option and put the value for the max ray distance in the cage extrusion field instead, and that worked!
Thank you for solving this on yourself. It’s part of the learning curve!
With each Blender versions, new problems arise or others are solved.
For us, some questions are asked so many times and giving the same answers is a lot of work. So we tends to point student in a direction, to try to solved it on their own. If it didn’t work, then they can ask for more specific help. I, like others, are also students, but longer involved in these courses.
