Recently I’ve begun using Hard Ops and Decal Machine
I’ve noticed if an operations fails in one, it will fail in the other.
So, contrary to the video’s put out by hard ops it’s not a bug with the addon.
There must be some way to diagnose what is happening.
In many cases,I can see it has failed just because of the faces of the cut object, I do not need
to remove the pieces to check the cut.
In other cases, the object being cut will disappear.
Is there a way to diagnose these problems by your result??
