I am trying to make a lava effect similar to the Taspir ffa map, but I am having some difficluty. I dont know how to make a brush that uses caulk_lava and has the lava texture applied to it. I'm also using a thin trigger_hurt brush right above the lavas surface. I am able to get visible lava that is solid, or invisible lava that is liquid, but I can't figure out how to get visible liquid lava. Any help is much appreciated, thanks.
Make the whole brush "Caulk_lava" then apply the lava texture on top. The trigger can be there but i prefer you to have a trigger as big as the lava brush, else you can crouch and you wont get hurt cause the trigger is over you.
If your trying to select only one face of the brush at a time, its control+shift+click.
Thanks for the advice, both comments are very helpful to me.
