Self-shadowing

I want to enable self-shadowing on the characters and enemies in the game. I know to go into doomconfig, but what is the self-shadowing command exactly called? (dont wanna screw up anything)

Also, how is the self-shadowing?

Find this string in the CFG:
seta g_showPlayerShadow "0"
and change the "0" to a "1"

Thats it.

I don't think he's talking about the player shadow here. Selfshadowing is when the stencil shadows cast by the models are drawn actually over the models themselves, as well as on the surrounding architecture and other models.

I'm unsure if there is any one variable to set this, but I did see a mod floating round which enabled them.

There's the mod.
