Interesting, useful glitch with Source SDk

[Death Injection]

OK, this glitch lets you cut holes in displacements extremely easily!!

First, select your displacement, then go to Texture Toggle Tool -> Displacements. Then set the checkbox to 'Smooth', the Distance to 0.00 and the radius to something above 65! Make sure 'spatial' is checked, too. Now when you 'smooth' a portion of it, that parts get deleted, giving you a nice hole!

Hope this helps!

Gonna try this, sound worthwhile.

Why not just use your clipping tool?
