I thought I might share this...
As some of you may already know, ProCore's ProBuilder and ProGrids are now an official Unity property.
They will be natively implemented into the Unity 2018.X cycle via the new Package Manager... free for
everyone (even for Unity Personal users). A more in-depth article exists on the official Unity Blog here.
Now this is good news for custom map makers!
I just tested it in-game yesterday with an empty scene, containing only a cube made with ProBuilder. The cube
was showing and so was the standard grid material on it. (So it seems to work in Warmerise).
ProBuilder is available on the Asset Store and supports "Unity 5.6.0, 2017.1.0, 2017.2.0, and 2017.3.0":

Cool! Never tried them before but I'll check it out and see if those tools are compatable with my brain. LOL
THANKS!
