I do not use Fuse but I did play with it a year ago when I saw it show up. I tried creating a girlfriend for mr Spock got it into Photoshop and created both an MP4 and a Gif, Took me a while to out how to do it but I was able to do it the day I looked ate it. Do not ask me to tell you how. I'm sure I do not remember. I did find the gif still on my system. The MP4 is better.
I may have made the gif from the MP4 it is newr than the MP4. You can edit an MP4 video in Photoshop and create frame layers from it than create a frame animation..... you save for web as a animated gif.
Actually, that's what I want. How to export it like GIF.
If your animation plays in the timeline. You can most likely render out a MP4 video. Close or leave open your Photoshop fuse imported document.
Open the mp4 video you rendered out of Photoshop into into Photoshop as a video document use the timeline fly-out menu to flatten frames to clips
delete the video group in layers palette
menu Make Frames from Clips
menu Convert to Frame Animation
Export>Save for web
Would be huge so I had save for web resize so the height would be 400 bicubic smoother GIF once to forever
But in that case, when you plug it in the web it will have a black background instead of a transparent one.
