@Arenas:
Add the "bindammotovar=X" option to the weapon's gunspec. Put a variable name in place of X. This is one of the special cases where you don't have to declare the variable first, since this will do it for you... and TADA!!! Your weapon's stock of ammo is now bound to that variable. Just change the variable when you want to change the amount of ammo that it's holding.
And just make sure you don't have ANY spaces when you're providing a weapon name. Spaces are what seperate parameters in FPI, so as soon as it hits a space, it thinks you're trying to give a new parameter.
@DonWON:
Unfortunately, I've yet to get layered FullScreen shaders implemented. At the moment, you may only have one shader active at a time.
If you're using the MB+B.fx shader, that may be a large cause of the slowdown when using the FS3... it does quite a bit more processing than your usual shader.
Glad to hear you're enjoying the mod, though!
The one and only,
