They have the following parameters: - **enableDeepOutput **– (Boolean) Specifies whether to include this render element in deep images. - **color_mapping **– (Boolean) Specifies whether to apply color mapping to the channel or not. - **consider_for_aa **– (Boolean) Specifies whether to consider this render element for anti-aliasing (may slow down rendering) or not. - **filtering **– (Boolean) Applies an image filter to this channel. - **derive_raw_channels **– (Boolean) Generates data in the raw channels by combining the respective color and the filter color channels. - **vfb_color_corrections **– (Boolean) Applies the post-render color adjustments made from the VFB. - **denoise **– (Boolean) Enables the render element's denoising, provided the Denoiser render element is present. ### **Shadows** --- The Shadows Render Element is useful for altering the appearance of shadowed areas in a compositing or image-editing application. Below are examples of possible uses. ![image](media://17269f13-0e55-448e-abdd-949b3b2c2e3e) Shadows darkened in composite using the Shadows Render Element `Raw Shadow x Diffuse Filter = Shadows` ![image](media://f735971e-4043-4a9a-8c15-cd1167581e08) ### **Raw Shadow** --- The Raw Shadows Render Element is useful for adjusting the appearance of shadowed areas after rendering in a compositing or image-editing application.

In the example, the lights in the scene are brightened and tinted with a warm tone. See the render before and after compositing. `Raw Total Lighting x Diffuse Filter = Total Lighting` ![image](media://72fa6190-89e1-4fb4-8206-8a79c65f8a44) `Lighting + Global Illumination = Total Lighting` ![image](media://d2c2d6f3-e377-4cad-a262-08a45eb7bb0e) ## **Toon Specular** --- Type: **RenderChannelColor** The Toon Specular Render Element is an image that stores Toon Specular reflection (highlights) information calculated from the Toon Material and Toon Material Node. The brighter the area, the more Toon highlight reflection the object exhibits in the render. Toon Specular highlights are colored if the Reflection Color parameter of a material is colored. The Toon Specular Render Element is included in the Specular Render Element. It can be subtracted from the main back-to-beauty composite, graded, and added back in. **Parameters** The Toon Specular Render Element is accessible through the *RenderChannelColor *plugin. - **enableDeepOutput **– (Boolean) Specifies whether to include this render element in deep images. - **name **– (String) Displays the name of the render channel. - **color_mapping **– (Boolean) Specifies whether to apply color mapping to the channel or not. - **consider_for_aa **– (Boolean) Specifies whether to consider this render element for anti-aliasing (may slow down rendering) or not. - **filtering **– (Boolean) Applies an image filter to this channel. - **derive_raw_channels **– (Boolean) Generates data in the raw channels by combining the respective color and the filter color channels. - **vfb_color_corrections **– (Boolean) Applies the post-render color adjustments made from the VFB. - **denoise **– (Boolean) Enables the render element's denoising, provided the Denoiser render element is present.
