NEW: Full support for Blender 5.0+! The addon has been completely updated to the new Extensions system. It brings a cleaner user interface, automatic scene setup, and more stable code for the latest Blender versions.

This addon is focused on Material and Object ID Render Passes. It works like a selection tool for post-production.

Motto:
“Making Color IDs simple. “
About:
CID stands for Color IDs. CID is used to easily generate Color IDs and Object IDs Render Passes (also known as ID channels/elements/masks). This output is often used as a cornerstone for creating Postproduction in other software.

How does it work?
The output is generated in the internal blender compositor as a Render pass.
Each material and object is assigned a random index number.

The colors in the compositor correspond to the given numbers.
The color range is limited to 2 arbitrary colors.

Basic information:
– Creation of Material / Object Render Pass setup in the compositor

– One-click random number generation for Material and Object Indexes

– Purchasing an addon includes future updates
