    Tips for Achieving Realistic Sky Backgrounds

    To make your sky background look even more realistic, consider these additional tips:

    • Add a Sun: Place a VRay sun in your scene to cast realistic shadows and enhance the overall lighting.
    • Use HDRI Maps: Instead of the default sky, you can use high dynamic range imaging (HDRI) maps to achieve more accurate reflections and lighting conditions.
    • Experiment with Camera Settings: Adjusting camera settings like exposure, white balance, and focal length can greatly impact the final result.

    With these tips in mind, you are now equipped to create breathtaking sky backgrounds in VRay SketchUp. Remember to experiment and have fun with different settings until you achieve the desired effect. Happy rendering!
