Wings 3D Development Forum

Hi,
The past few days,I checked boolean operations under some face attribute combinations.
(For example the faces that has hidden,hole,invert and/or conditions with complex etc...)
Some worked normally, and some output crash logs.

Other than that,an interesting result was obtained by unioning objects whose inverted normals.
(Actually several steps are necessary to get this result. invert and separate)
I think that it is useful even if there is "engraved edge" with the Boolean command.

tkbd thanks for such effort to check all the possibilities in which boolean could to fail.

I just don't know when they will be fixed, but at least it's working fine for regular objects. The situation involving objects with inverted normal is an atypical situation.
