Octane ROP Output Tab Parameters

Render To MPlay - Sends the beauty pass to MPlay for rendering. MPlay opens with a Gamma setting of 1.0 to avoid a double gamma correction due to the OctaneRender®-native gamma and color mapping settings.

Overlay Render Stats While Rendering/Overlay Render Stats While In The Final Image - These options overlay OctaneRender rendering statistics while rendering them or leaving them in the rendered image.

Overwrite MPlay Frame - OctaneRender uses MPlay as a frame previewer while rendering a sequence. Disable this option to store all the rendered frames in MPlay for playback, or for saving the animated sequence from MPlay once the rendering is complete.

MPlay Gamma - Adjusts the gamma value if rendering to the MPlay window. 

Color Space - The color space chosen for the output rendering, from the list supplied in the drop down menu, as follows:

  • sRGB - a color space developed by Microsoft and HP in 1996, standardized in 1999. Variations of this color space by many vendors, including Adobe, form the basis of the way the color is typically presented on computer screens. This color space is not capable of accurately representing the spectral color in with Octane renders; it is a better choice to use the OCIO <sRGB> output option if you need sRGB color imagery. sRGB color space is non-linear, and has a gamma curve of 2.2 applied.
  • Linear sRGB - essentially the same as sRGB, but with no gamma curve (gamma 1.0). This setting will make images look darker. As all renderers operate in linear space, colors are more accurate. Prior to the introduction of the new ACES-based color management system in Octane, this was the best output option for color grading and compositing pipelines.
  • ACES 2065-1 - ACES stands for the Academy Color Encoding System, developed by the Academy of Motion Picture Arts and Sciences. The 2065-1 designation refers to the specific flavor of ACES; 2065-1 is the ACES archival format, effectively the broadest color space supported by ACES. Most ACES/OCIO applications can import this format; typically, the format is transformed into the application's working format (often user-specified as opposed to hard-wired into the application). Use this format if you want to retain as much of the original Octane spectral space as possible.
  • ACES CG - ACEScg is a specific version of ACES developed for RGB rendering engines. As Octane is not an RGB rendering engine, this format is not necessary, and will result in less color fidelity than ACES 2065-1. However, some production pipelines require ACEScg, therefore the format is presented as an option here.
  • OCIO - This menu presents many different output options determined by the OCIO config that is currently set in the Octane Settings > Color Management tab Config file slot(s). For more information on OCIO, see here. For typical sRGB uses, choose the OCIO:Output/Output-sRGB option.

OCIO Color Space Role - (Only available if OCIO is selected as the color space) - This button will present a menu of available OCIO color spaces from the assigned config.ocio file.

OCIO Look - (Only available of OCIO is selected as the color space) - The items in this menu are generated from the information in the assigned config.ocio file.

Force Tone Mapping - Tone mapping will approximate a high dynamic range by adjusting luminance and saturation values in an image, adding more detail and contrast. Tone mapping uses gamma correction as part of the process but is different than color correction or color grading, where color LUTs (look up tables) are used to create a certain look. Tone mapping is irreversible once applied if saved. This option is inferior to the ACES/OCIO system. This option should only be used when matching older OctaneRender scenes.

Premultiplied Alpha - (only when saved as EXR) - Determines whether to multiply or premultiply the rendered images.

Output Image Files - Enable this option to save the rendered images using the native OctaneRender file functions. The available formats are Multilayer EXR, EXR, and PNG.

Create Intermediate Directories - Create intermediate parent directories for output files.

Image File Path/Prefix - The path where the resulting images are rendered. Include $F in the file name to insert the frame number.

The file name also supports the custom $OCTANE_PASS variable to add the render pass code, and the custom $OCTANE_LAYER variable to add the current rendered layer ID.

File Format - Selects the image file format. Available formats are Multilayer EXR, EXR, and PNG 8/16 (tonemapped or not tonemapped).

Deep Image - Enables deep pixel image rendering for deep image compositing.

EXR Compression - Configures the compression parameters for EXR files.

EXR DWA Compression Level - Configures the compression level for EXR files.

TIFF Compression Type - Configures the compression  type for TIFF files.

JPEG Quality - Configures the compression quality for JPEG files.

Save Layered EXR - This option will save AOVs in a single layered EXR file.

Save EXR Deep File - When rendering deep files, this option will save the deep file in EXR format.

Deep File - When you click on the Save EXR Deep File checkbox, OctaneRender uses this file path to save your deep file.

Save Noisy Image when the Denoiser is Enabled - Saves the noisy image along with the denoised image. 

Render Object Layers - Separates scene geometry into parts, where one part is meant to be visible, and the other parts capture the side effects of the visible geometry on it. The layers allow different objects to render into separate images, where normal render passes can apply. Use this option to enable the layer rendering.

Layers To Render - Defines the layers to render in the scene.

Layers Mode - Provides control over the types of layers to render. There is more information about render layers in the Render Passes topic of this manual.
