Orbit tool and shadows

[allison22]

when I use the orbit tool on some SketchUp models with ground shadows on, the shadows and sometimes the model's texture disappears while the camera view is moved. Everything reappears when the view is stationary again. On other models, everything remains intact. I originally suspected that the more complex models were taxing the capabilities of the graphics card and computer, but I've found no correlation with this problem and the size or complexity of the model - the problem occurs with some very simple models and does not occur
on other very large models. Any idea on what's causing this behavior ?

Allison, this is normal behavior. SketchUp can temporarily stop showing shadows and textures while you are navigating in the model to improve navigation performance. If it didn't, it would have to re-render textures and shadows many times while the camera is moving which would slow things down a whole lot.
