lol, ya this is such a pain to deal with. The cliffs jut out at the base and its hard to completly block to keep players out. I'm just keeping my fingers crossed that valve will fix displacments... I might be waiting for a very long time.
I can imagine it, but you can shape the playerclips to look like displacements.. Maybe copy the displacements and apply playerclip to that. Enlarge it by like .01 so it just covers the displacement.
The displacements are their own entity. You can't turn them into a playerclip brush, as far as I know. Even if you applied a nodraw texture to them or something, you'd still get the same issues with falling in cracks.
Perhaps you could try the oldfashioned triangulation(http://www.snarkpit.net/editing.php?page=tutorials&game=HL&id=16) to make the playerclips more into the shape of the displacement. But then again it would be just easier to add a trigger_hurt behind the displacement in terms to kill the damn exploiters.
Yeah you cant. I tried experimented with different ways, the best way i found so far.. is applying a blank transcluent texture to a displacement and minus 1 unit from each sides This works!!!!!! Ill post a .vmf example view attachment. Then i wonder what the performance would do.. hmm
