Yeah good work on actual animations. I meant most people just make a stance for standing still with a lightsaber, that's the first thing I did. You skipped that and succesfully implemented a whole new grip animation with flailing suspended person. That's going big! Yeah rotating the bone called 'r_hand tag' with the white or green slider will flip the saber upside down. That will make your animation much better. With push and mind trick you don't have to start over necesarily. You can set some of the bones to blend and that will make them smoothly transition. Blending is when you click the little gray box next to the +/- box. It will put a little dot in the box and that means it is blending.
Say I wanted to make a guy slowly lift his hand smoothly. I could make two frames one with the hand down and one with the hand all the way up. Next I would put some blank frames between the two frames and set them to blend. Now the hand will move up slowly. So for drain just make the feet once for the first frame and again for the last and set all the other frames to blend the legs and that's all there is to it.
When I made a swing that is the method I used. It's referred to as "key frames" and "inbetween" frames. The key frames are the ones at the start and stop of a motion. Anytime there is a change in motion there should be a key frame. Then you insert inbetween frames that blend the two keyframes together.
I was woried about filesize, i actualy thought of re- merging one animation for the Humanoid, but was woried it would take several MBs or something then........
