The lava in Doomsday already glows, though no where near as much as Quake.

One can modify the glow in materials.ded found in "Defs/JDoom/Doom1", inside JDoom.pk3 (which can be found in "Data/JDoom").

You don't need to modify the definitions to increase their strength; open the control panel, navigate to the lighting tab and there you will find a Glow Strength slider - move it to the far right for maximum strength.
