I decided to make a few random textures
Long story short I found the emboss tool and made a way cooled lava block, with emission on it looks really cool
I tried to make some graffiti
I am not really sure what I was making here, It looks kind of like grass and glass tile
The three textures side by side in Unity, added an emissive color to the lava
