Why we like it

Id Color Pass earns its place for reducing a coloured ID pass to a handful of compositor steps built around a single appendable node group.

What is Id Color Pass?

Id Color Pass is a node-based method from Luiz Kowalski for generating a coloured ID pass inside Blender. It centres on an id_pass NodeTree that you append into your own file, then assign an ID to each object or material.

The workflow runs through Blender's compositor. You enable IndexOB or IndexMA in the Render Layers Properties, switch on Composition Nodes, and connect the id_pass group after the IndexOB or IndexMA output on the Render Layers node. The result is a coloured ID pass.

It targets Blender 2.79 and is released under the GPL license, with documentation included. The listing records 80+ sales on Superhive, and it's shown here as free. Check the developer's page for current licensing and any compatibility notes beyond the listed version.

Who is Id Color Pass best for?

Id Color Pass is best for blender users who want a coloured ID pass generated through the compositor.

How much does Id Color Pass cost?

Id Color Pass is completely free to download and use.

Frequently asked questions

Does Id Color Pass work with Blender 2.79?

Id Color Pass is listed for Blender 2.79, the version noted on its store page. It's distributed under the GPL license and works as a node setup you append into your own file rather than a standalone add-on. If you run a newer Blender release, check the developer's page for compatibility details before relying on it, since 2.79 is the only version confirmed on the listing.

How do I set up Id Color Pass in Blender?

Id Color Pass follows a compositor-based routine. You append the id_pass NodeTree into your file, then assign an ID to each object or material. Enable IndexOB or IndexMA in the Render Layers Properties, turn on Composition Nodes, and place the id_pass group after the IndexOB or IndexMA output on the Render Layers node. Rendering then gives you the coloured ID pass. Documentation is included to walk through the steps.

What license is Id Color Pass released under?

Id Color Pass is released under the GPL license, according to its store listing, and it's shown in this catalog as free. Pricing and licensing can change over time, so check the developer's page for the current terms before downloading. Because it relies on Blender's own compositing nodes and an appendable node group, there are no extra dependencies called out beyond a working Blender install.

Do I need to enable Composition Nodes for Id Color Pass?

Id Color Pass depends on Blender's compositor, so Composition Nodes must be switched on for it to work. The setup routes the appended id_pass group after the IndexOB or IndexMA output on the Render Layers node, which means those index passes also need to be enabled in the Render Layers Properties. With both in place, the group turns your assigned object or material IDs into a coloured ID pass.
