I'm looking into getting into 3D myself as well, these look interesting ! I remember reading about those on the GMC, links still work.
You are telling him to use those LIBs, well they don't work in ENIGMA. They show up in the action libs, but using them does nothing.
I even tried the Basic3Dexample.gm6 file that comes with one of the libs (from first link)
(had to change name of object from 4WallBuilding, to FWallBuilding, as it did not compile otherwise.
After doing so, it compiles fine, but no 3D..
I can only see the text at the top of each room but the screen is empty.
Too bad because the LIB looks great for getting into 3D (the basics).
And yes I have the latest drivers, and yes I have the DX runtimes,and yes I tried everything to be tried !
