Yes, I read it, and I even tried to replicated it, but in my end, Booleans work as usual.
C4D is special because you can sorta work like “Houdini lite”, nesting objects with parametric extrusions, sweeps, and on top of them use a boolean operator. Sometimes the best advise is to convert your parametric object into a mesh (Current state to object) but you loose the ability to change it latter.
The only thing I can think of, is if the OP is trying to Boolean a Text (with the new bevel tool), we all know bevels on text tend to add a lot of small geometry than can crash a boolean operation (I had to test this in R21)
I have used Modo very little, but I thought Mesh fusion meshes couldnt be exported outside Modo ( I used it when it was a plugin for Modo). I love the LiveBooleans in Zbrush and the Zmodeler (very different workflow from the usual pulling / pushing vertex). Im going to have a look at the Nitroman video, although I dont think its at the level of Boxcutter.
