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. This can allow multi-pass rendering and generate particular person EXR information for every cross you outline.

Here is a desk summarizing the advisable EXR channel settings for widespread 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 cross you wish to render, create a separate render layer and assign it to the corresponding EXR channel. This can generate a separate EXR file for every cross, permitting you to isolate and manipulate particular person parts.

3. Set Render Choices

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