When building tree supports, flat tree geometry created inside object that comes outside

Hard to describe this, as the thread title shows 🙂 On some models when I generate tree supports then convert to solid, there is this extra flat geometry that is created and runs from inside to outside the model. It is reproduceable, some times I can find the source of the tree it came off of and delete it , other times I cannot. I tried messing with the Solid Min Offset setting but it still happens. I have attached a couple of pictures, the first shows the weird flat tree running. The second you can see it peeking out of the sides of the model .

99% of the time it's happening because of a flipped normal/non manifold mesh. 1% the time the MM algorithms just mess up. When in doubt, remesh.

I use the orientation to find the low overhangs before running the supports, and in this case it was flipped upside down. So you mean this happens because its been rotated? Is there a way to prevent this (other than not rotating the model)?

No not rotating the whole model. Non-manifold means mesh errors.

Flipped normals means one of the faces of a triangle or cluster of triangle is the wrong way.

The orientation tool rotates the object to a position that minimizes the total amount of overhangs, but this often results in an illogical orientation that is not the best. I'd rather just use $2 more in filament printing a few more supports.

Ok thank you for the information!
