Cryengine 3 (3DS Max bone export problem)

[jackneeson]

Hello,

I have a problem exporting my weapon animation in 3DS Max. (I'm using the 2011 version) When I have unchecked the "Allow Object Bones" when I go into the Cryengine 3 exporter and select root on my weapon rig, it does not allow me to place it. I can click export when I say "Canceled By User".
Any reasons why this is happening? Do I need to use a later version of 3DS Max? Or have I done something wrong earlier in the process?

Any help will be apprecited.

I did not find the right solution from the Internet.
