Claus_N Thanyou for your help.
The entity, or view entity, of my gun i defined the next way:

entity gun0
{
type = <el_revolver.mdl>;
ambient = 0;
pan=90;
x= 5;
scale_x=2;
scale_y=2;
scale_z=2;
layer=1;
y= 3;
z= 0;
ammo=0;
numbergun=1;
recargar=1;
}


How can i define it like a real entity in the world space?
o how can i turn off the lights of the view entity?

thank you friend.
