I've tried to find the arms in the character editor but nothing will work. Any suggestions?

If you mean the character file location for the arms, it's:
Objects/Weapons/Arms_Global/arms_nanosuit_**.chr

The ** being either us or asian.

When I add an attachmnt it doesn't show on the arms ingame.

^in all my levels always shown, maybe problem with its position? In that folder you will find some about 6 models of arms - try any other. It must work good! Or you mean charAttachHelper to that arms model?

If I'm understanding you correctly:
It wouldn't, as you can't save attachment information directly to a .chr file, instead having to save it as a .cdf with the game still loading the unmodified .chr file. If you save it as a .cdf with your attachments added, next step would be to open player.lua (Scripts/Entities/actor) and change the fpItemHandsModel parameter from chr to cdf.

If that's not what you mean please elaborate on what you're trying to do.

^Callofduty511 - youve made me upset. I thought he makes simply file of chanels using character editor or trying to make animated arms at least.:]

ALso ^ JasperHope, if you need arms (animated!!!) i may give a FG to use anim object as if that were real players' arms instead of players' (first person) real arms. But any way i cant understand what your idea is about

Andreyyou musn't have read my posts. I want to add an attatchment to the first person arms - god knows where you got animating them from ;P, thanks for trying anyway .

And I think that might work, callofduty, thanks .

I'm surprised nobody has ever tried this before... I guess it could be possible to just export the arm model with the attatchment from 3ds and switch between models ( if that's possible ).

^LOL :] I saw words "character editor" and forgot about everything around. Sometimes it happens with me.

Jasper do you fix this problem?
If yes, can you tell me how? i have this problem too.
