The using { /Fortnite.com/Devices } Class has a MoveTo function you can use, You can supply the position by passing it from the Prop you want to rotate, and change the rotation by passing a different rotation value, The last parameter is for how long it should take. Here is some suedo code that can help you get started. Look into the spatialmath Module for more guidance.
#Setup Basic Transform Information
set PropTransform = PropToRotate.GetTransform()
set PropPosition = PropTransform.Translation
set PropRotation = PropTransform.Rotation
I did notice the setting was grayed out. It is something simple that you would think doesn’t need to be overly complicated but here we are lol. On that note, I don’t think Verse even has a constant for PI so if you need the prop to stop exactly where it started (360 for example) it likely wont.
