Non-climbable Walls

[tojimaru]

How do you make walls not climbable by dretches (or any other wallclimbing aliens)?

[Bissig]

slick_shader or something like that.

[tojimaru]

Can you explain? I don't know much about shaders.

[your face]

go to karith-->solidslick, or, common-->slick

solidslick ftw, basically playerclip with slick

You should go through the tremulous gtkradiant wiki at least once. You will not learn everything about gtkradiant but it helps get started (from there on google is your best friend). And even if you don't soak in all the information you'll know what's out there and when something comes up you can google it (because you know it exists).
