I am using SketchUp 2023 and have started using Fredo6 animator. I have used it to fly around and open doors within a building model ok. Now for some reason I cannot get the animation to run showing the movements on screen. The animation timeline at the bottom of the screen is running but the images are not. Any idea would be fantastic
