# reflectionResolutionScaleFactor The resolution scale factor of the offscreen buffer that SceneKit uses to render reflections. ``` var reflectionResolutionScaleFactor: CGFloat { get set } ``` ## Discussion SceneKit creates a reflection effect by rendering the scene twice. First, it renders the scene into an offscreen buffer, using a point of view whose position is the reflection of the camera’s position. Next, it renders the scene from the camera’s point of view, using the offscreen buffer as a texture map for the floor’s surface. Rendering the scene twice incurs a performance cost. Reducing the resolution of the offscreen buffer reduces this cost but causes the reflected image to appear blurry. The default scale factor is `1.0` in macOS and `0.5` in iOS. --- Copyright © 2026 Apple Inc.
