Are you talking about the SD3 lava that Radien used in the DoR set? Or is there some other mystery lava I don't know about? O:
Once upon a time, I made a 4x4 lava tile(s) in Gimp, or whatever, and attempted to use palette cycling to give it a glow effect. If I would have used this, I would have used special lava edge pieces that I would layer over the lava. It looked something like the Majora's mask lava. Unfortunately, using the lava was kind of demanding since it required an entire C-set, and coupled with the would-have-been palette cycling, it was just too much.
