Monsters.Ded / translucence

[saducimus]

I thought it would be interesting to try and make some
monsters translucent like the spectre.

Here's the difference between the Demon & Spectre
In monsters.ded:

DEMON
Model {
State = "SARG_RUN1";
Scale = 0.35;
Md2 {
File = "pinky.md2";
frame = "run1";
Flags = "df_selskin";
Selskin mask = 0x7;
Selskins {3 3 2 2 1 1 0 0 }; };
SPECTRE
Model {
State = "SARG_RUN1";
Selector = 1;
#Flags = "df_darkshadow";
Skin tics = 2;
Scale = 0.35;
Md2 {
File = "demon.md2";
frame = "run1";
Skin = 1;
Skin range = 6;
};

So I tried changing the flags for the hellnight to "df_darkshadow" with the # in front but game merely crashed.

Any ideas?
