Hey guys, I got some custom weapons from NPI and how can I make my Green Lanterns spawn these weapons for use in-game?  I'm sure in the Crisis mod, Hal Jordan was able to spawn some light posts as wieldable weapons, how about with custom ones then?

Easy to do, but you need FFX to do it, which is what that mod used.

Yes, the Plasma Sculptor attribute, but I also need to change to make a yellow colored effects.  I don't know where to start with this. :(

I believe all the information you seek is all 'hidden' in the ffx documentation, so start there. Getting yellow objects and effects requires recoloring or finding them (and I know some exist).

Indeed the FFX manual is always a good starting point for info on FFX features. ;)

As for the yellow version, Taskmaster has provided them: http://ffx.freedomforceforever.com/downloads.htm
