I don't making lava a water texture makes much sense unless you're doing some type of volcano like map which would need some type of bubbling lava. Having a just a black rocky testure with orange glowing cracks in it.
Youme, I do love that floor texture. Are you going to make it public?
...well I guess I missed that part heh.
EDIT: though if it's inactive then you wouldn't expect there to be bubbling lava in it.
