I used these viewhands and followed the instructions  - http://www.cfgfactory.com/downloads/show/5883b450c139a

All the materials and the xmodel are rigged together and I can see them just fine in assetviewer but when I load up my map the viewhand model is there but they are completely black - https://imgur.com/a/EgTbsAH

I have searched this forum and zombiemodding up and down but no one else seems to have this problem.
