All of the textures produce light which I tried to show with the quads behind them. The textures came out looking a little off in 64 pixels but look much better as you raise them
A rusted and metallic tile with a glow in between
An attempt at a block of lava and rock
A light with some stains to block the light
The same tiles, at a higher quality, the white is where the emission comes from
The lava, at a higher quality, the white is where the emission comes from (Looks really cool with emission)
Same old ceiling light tiles, at a higher quality, the white is where the emission comes from, the stains are like little bits of metal (because I though it looked cool)
