      • Limits

    • Objects tab

      • Candidate objects: * (all)

        • Using bundles - @bundleName

Settings

  • Pixel samples — antialiasing (higher values = less noise)

  • Samplings — noise levels

    • Min Ray samples

    • Max Ray samples

Jason iversen PBR

  • Pixel Samples: 7x7 (up to 10x10 if the scene really needed it)

  • Min/Max Ray Samples: 1/9 – sometimes 2/9

  • Noise Level: 0.08 (this seemed good enough to us … less than film grain)

  • Reflect/Diffuse Limits: 2, 2

  • Color Space: Gamma 2.2

  • Color Limit: 4 (your 1 is clamping way too hard)

  • Photons: 2m photons for a huge room. Yours is 7m! I'm sure 1m is fine for this space. Ratio was 2.5.
