I can't seem to find a way to visualize a layer in animation and have it appear with swipe effects.
According to the animation help page https://pro.arcgis.com/en/pro-app/help/mapping/animation/animation-properties-pane.htm it should be rather easy to find, on the Keyframe tab of the Animation Properties window. But I can only see transparency options/settings for layers, nothing for swipe settings.
Am I missing something obvious?
