so i spent more than 2 months on porting guns to waw... i've learnt to do it really good but i still encounter problems than i cant fix so i was hoping you could give me some help with the situation.......

1) i ported the peacekeeper to waw (models anims and everything)...... so i went to the game and got the peacekeeper but only the viewhands were visible, the gun wasnt..... so then i tried to port the peacekeeper with a silencer and for some reason the gun was visible..... how can the peacekeeper is invisible and the peacekeeper suppressed wasnt? how can i solve it...??? (that same problem happened with the bo1 spas12)

2) i ported the bo2 mp7... when i went to the game the gun was visible THANK GOD but there were missing meshes from it (especially the mp7 was missing the bolt).... same problem with the saiga12 and the hk416........ missing meshes... its really frustrating... how can i solve it????

3) i ported the g36c from mw3 ..... and when i went to the game the second mag was floating in my front of me although on maya in the animations the mag is behind the tag_camera, far as well.......
how can i solve it ? xD
