Looking at this further, it looks like I’m just adding a new Less Than node. Can it really be that easy? Based on your graphic, I’d add the node up in my Crackle Mask frame and run a noodle from my displacement color ramp up to it. Then I’d combine the output from the Less Than node and the output of the color ramp in the Crackje Mask using a Mix RGB node. THEN, I’d plug that result into the bottom slot of my Multiply node to connect it with the Lava Pool mask. it sounds confusing when I write it out but it looks right in my head.
