Are we talking about the same build (104261)? I just checked several of the animated scenery assets in that list and none of them are animated in 104261 Surveyor (but they are in TANE Surveyor). Does 104261 have a Pause control in Surveyor? I thought that was only for the TRS19 Plus version. I certainly could not find any Pause control.
Yes...Build 104261
Pause control is under the Tools Menu -> Pause
All animations worked fine for me in Surveyor once you un-ticked the Pause control.
