Hi @3500741,
Great question!
There is not exactly a way to change the background in the animation environment. But there is another solution!
I found this video that shows how to make a video rendering from the render environment. This is a great way to get high quality animations of your design. A few notes about this video:
- If you haven't made a motion link before, you might check out this video which shows you how to make a motion link from joints. If you haven't used joints before, check this out.
- The UI has changed a bit so if you are going to make your rendering into a video, you need to select "video", let it render, and then you will have the option to render as a video. I made a screencast so you can see the process from after you have your motion study and your scene settings set up. (I skipped the rendering times, yours might take a little longer after hitting the "render" button).
- The render I did was a bit slow, it might take some playing with the motion study to get the look you want. You can always go and edit it in a video editor as well if necessary.
If any of this doesn't make sense, please feel free to upload your design and I can make a more detailed screencast or explanation for you.
