Hey all, I found this a few months ago you might already have it on here but new members cant search threads so fuck you too.
you can use mat_slopescaledepthbias_normal as a wallhack, kind of ghetto since models look funky, but it's a DirectX commad so it works in all HL2 based games (and maybe some others)
basically if you set it to a small negative number you get wallhack
sample bind:
alias +view "mat_slopescaledepthbias_normal -0.0001"
alias -view "mat_slopescaledepthbias_normal 0"
bind "x" "+view"
bind "-" "mat_slopescaledepthbias_normal -0.0001"
press x for temporary x-ray vision, press - for permanant.
You can change the value (-.01 to -0.0000001 works) to cahnge how 'deep' you see, but the deeper you see the more fucked up the modles are. Try it and you'll see what i mean.
Happy raging
