Baking errors in Substance Painter.

I'm getting these baking errors when trying to bake in SP.
Any idea what's causing the errors?

Are you sure those are baking errors ? To me it looks more like the polygon is missing.

Looks like you have some alpha there?
EDIT: ah wait, that might not be it, because I can see the seam on the last image.

Thanks for the replies.

The errors seem to have gone away when I baked without a cage.

I didn't realize I could get a perfect hard-surface bake without a cage.
