What are the best render settings?


Generally, in Corona Renderer the default render settings should perform well in most situations so usually there is no need to change them. However, some special cases may need additional tweaking of render settings. There are no "universal" settings that will always provide best results.


You can follow these simple guidelines that should help in most common cases:

  • Use UHD Cache as secondary GI solver for interiors and scenes where global illumination is dominant

  • If you are rendering an interior scene with small window holes, always use portals (3ds Max | C4D) and if that does not help, increase GI vs. AA balance (3ds Max | C4D) and/or Light samples multiplier (3ds Max | C4D)

  • If you are dealing with strong noise caused by direct light, increase Light samples multiplier (3ds Max | C4D)
    See: How can I tell whether noise comes from direct or indirect light? (3ds Max | C4D)

  • If you are dealing with strong noise caused by indirect light (GI), increase GI vs. AA balance (3ds Max | C4D)
    See: How can I tell whether noise comes from direct or indirect light? (3ds Max | C4D)

  • If you are dealing with noise visible on glossy reflective surfaces, increase GI vs. AA balance (3ds Max | C4D)

  • If you are dealing with bright spots visible in refractive objects, decrease GI vs. AA balance (3ds Max | C4D)

  • If you are rendering a scene with strong depth of field (3ds Max | C4D) or motion blur (3ds Max | C4D) decrease GI vs. AA balance (3ds Max | C4D) to about 4-8
