Thanks Poserpro... Can you let me in on the secret...? LOL I am recording a dance. When I playback the dance in Dance studio it is there. I export the BVH. I then replace all the instances of _ with a space, as per tutorial by Steve Shanks. If I open the BVH in a text editor it is a very small amount of text. It ends with: MOTION Frames: 0 Frame Time: 0.033333 Hmmm... Anymore help greatly appreciated... Colm...
