I made a character in character creator with weapon assessories stand-ins, When I send to IClone I can animate the weapons movement on the hips and in the hands. But when I send the character with assessories to 3DExchange the props are there but when following the instructions on saving animation and props draging the imotion into 3dx is causing my props to scale but it does not animate. Even if I export the FBX from iclone the prop does not animate in the export. I also made sure that I flatten the frames. 

Here is a video of what is happening. 



I used this information here:
