Winner users may notice minor visual distortion in rendered images. This digital noise in pictures can be seen as trace appearances of random pixels and variations in the brightness or colour of the render including chromatic aberrations, otherwise known as colour fringing. The effect is similar to grain in film photography as both can cause images to appear grainy.
What causes digital noise in Winner?
Digital noise in Winner can occur when the user's lighting settings for renders are too dim, or too focused in a single location. Digital noise is also more likely to occur on or around metallic surfaces and glossy surfaces, which reflect more light. See below for an example of a render with digital noise present and a render without digital noise present.

How to reduce digital noise in Winner
Users should first try increasing the light intensity of the indoor and outdoor lighting in the user's plan. For more information, see Define light profiles and Light source properties.
Noise reduction tool
Users can also use the Noise reduction slider in the Render quality settings and the 360° rendering settings windows.
This setting can be adjusted between Off and High. Having a high noise reduction setting will increase the time it takes for an image to render, but not substantially. Using a high noise reduction setting may also cause a rendered image to appear blurry. However, this can be offset by increasing the Sharpness in Tone mapper settings window. For more information, see What are Tonemapper settings used for?
To adjust noise reduction settings, at Alternative level:
- Right-click the Perspective view window.
- Select Perspective > Render view settings.
Note: Or press Ctrl + Shift + R on the keyboard. - Left-click and drag the Noise reduction slider.
- Click OK.
Note: For adjusting 360° rendering settings, see How to create a 360° panorama.
