for you guys who wanna make ROTS-like lava in photoshop, try this out


choose medium brightness orange

black background color

filter-render-clouds

filter-render-difference clouds a few times

up the contast (enhance-adjust lighting-brightness/contrast) until you see reds, ornages and yellows but not too much

use filter-sharpen-unsharp mask to the settings of your choice and there you go, pretty good looking lava

(i used elements 3.0 so yours might be different
