The default settings for Revit’s realistic visual style are dark and dreary. But if you look at the top of the visual styles menu, you’ll see “Graphic Display Options…”
Open Graphic Display Options and then expand the Lighting panel to see sliders that will allow you to adjust the brightness of the sun, ambient light, and shadows in your scene. Experiment to see what look you like – I used these settings to get a nice sunny mood. If you have one version you want to use in most of your projects, make the adjustment in your project template.
Do you have a favorite setting? If so, leave a comment!
