2. Allow Multi-Move Rendering

Go to the Render Settings window (Cmd/Ctrl + B) and navigate to the “Output” tab. Within the “Format” part, choose “Multi-Move EXR Sequence” from the dropdown menu. It will allow multi-pass rendering and generate particular person EXR recordsdata for every go you outline.

This is a desk summarizing the beneficial EXR channel settings for frequent passes:

Move	EXR Channel
Magnificence	RGBA, Z
Diffuse	RGBA, Diffuse Weight
Specular	RGB, Specular Weight
Regular	RGB, Delta Regular
Reflection	RGB, Reflection Weight

For every go you wish to render, create a separate render layer and assign it to the corresponding EXR channel. It will generate a separate EXR file for every go, permitting you to isolate and manipulate particular person components.

3. Set Render Choices

Alter the render settings to optimize the standard and efficiency of the multi-pass rendering. Contemplate growing the pattern rely, enabling anti-aliasing, and adjusting the worldwide illumination settings.

Folks Additionally Ask About C4D How one can Set Up a Multi-Move AOV EXR Sequence

Why use a multi-pass AOV EXR sequence?

A multi-pass AOV EXR sequence gives larger flexibility and management in post-production. By having every ingredient rendered out individually, you’ll be able to independently alter colours, lighting, and different settings with out affecting the complete scene. That is particularly helpful for advanced scenes with a number of components and supplies.

What file codecs can be utilized for multi-pass AOVs?

Cinema 4D helps EXR (OpenEXR), PNG, and TIFF codecs for multi-pass AOVs. EXR is beneficial for its excessive dynamic vary and adaptability.

How one can configure AOV settings?

The AOV settings might be configured within the “AOVs” tab of the Render Settings. You may set the colour house (e.g., sRGB, Linear), bit depth (e.g., 16-bit, 32-bit), and different choices relying on the AOV.
