Any chance on making Vulcanus' molten lava emit some light? One of the images shows an immediate line between a lava pool and pitch black ground.

I'm unsure if this is possible in the prototyping stage, so the only way I could do this would be placing lights on every lava tile during runtime. I'm like 99% sure this would be a horrible way to do it, so it's unlikely I'll be able to add something like this.

Lava glows because it has a sprite that renders as a glow, not because it has a light source that I can just set to be bigger. If someone knows of a way to change this then it'll definitely be something I try to add. (Probably also to things like heat pipes too, as I imagine it uses the exact same sort of logic)

Yes, I guess if you were able to make the lava glow, suddenly we'd have glowing water, heavy oil and ammonia on other surfaces. :D

Well not necessarily. Afaik there isn't anything particularly different between land and water tiles, they are all just TilePrototypes in the end. Changing lava wouldn't affect water etc.

The issue is that I don't know how to tweak the lava to have an actual light source, if it's even possible. I've had a fairly good look at the TilePrototype docs, and nothing useful stands out aside from the glowing sprites. (And unfortunately, glow isn't a light source)
