Love the rolling ball game :) I did this in USD Composer last year as well as an exercise but did not run into this issue so I am curious if you might have a script attached to the cubes that are resetting their positions. Feel free to share your USD Scene with me as well and I can take a look
Yes, I agree about the script. Curious. I see a “scripts” folder right there in your Content Browser. The only way to be sure is to build this scene out again from scratch. Or just look through that stage tree and delete any scripts or actiongraph. I see that “PushGraph” there, which may indicate some animation track. Please delete that.
