Saving 8-bit Images with ACES/OCIO


ACES and OCIO can be used to output tone mapped 8 and 16-bit images that effectively match the highest quality 32-bit output. These 8 or 16-bit images will not have the latitude of a full 32-bit image, however. This tone mapping is handled by ACES/OCIO directly; the original tone mapping in Octane should NOT be used for this.

The illustration below shows the proper settings required for 8-bit image output with ACES. Set the Buffer Type to LDR (8-bit) and set the Color Space to **OCIO > Output > Output-sRGB.** This output will match the result in Live Viewer with the image saved from Live Viewer, when using OCIO. Save via the standard Cinema 4D Save panel and options.

Saving 8-bit Images with ACES/OCIO

- Camera Imager in Live Viewer should be set to ACES sRGB
- Live Viewer should be set to the OCIO setting
Live Viewer is used to verify the final render output, so these settings need to be accurate.

- Set Buffer Type to LDR (8-bit)
- Set Color Space to OCIO:/Output(Output - sRGB)
- Optional: ENABLE Use Denoised Beauty Pass
- DO NOT USE FORCE TONE MAPPING
