Alright...is there a lava SHADER, not a texture? I found a texture under basic, but no shader...anyways, I tried applying water-shaders to the top of my lava caulk...and guess what? It worked! WooT! Thing is...no lava shader to use! So...where is it?
i think theres a fog you can use in guess what? 'fogs'
also in common theres some lava thing
