The rotation is easy enough with the FloatFieldInterpolator node. The issue is you can't apply a mask (to hide the part of the circle image at the top of the rotation) that is supported on all devices. From the docs: "MaskGroup nodes do not work on all Roku players (specifically, MaskGroup nodes only work on players that support OpenGL)." https://sdkdocs.roku.com/display/sdkdoc/MaskGroup
Or is there another way to achieve this animation?
