Checker earns its spot as part of the Zen UV add-on, pairing node-based checker application with custom checker sets and resolution filtering for UV inspection.
Checker is a Blender add-on for checking the state of UVs on a model, and it forms part of the wider Zen UV add-on. It works through a node-based system that applies checker textures to the model without ruining existing materials or adding new ones, so you can inspect a mesh and step back out again.
The tool ships with Zen UV Checkers, a set of color and monochrome patterns designed to read clearly across different texture sizes. A Filter Resolution System sorts existing textures by resolution and by square or rectangular format, and you can add your own checker texture or an entire texture library. A UV Maps Properties Tab keeps UV map management within quick reach.
The interface centers on a multifunctional main menu, and documentation is available on the developer's page. A demo video is also available for anyone who wants a closer look before installing.
Checker is best for blender artists who need to inspect the state of UVs on a model using checker patterns.
Checker is completely free to download and use.
Checker lists support for Blender versions 3.6 through 5.1, covering a wide span of releases. It's distributed as part of the Zen UV add-on, so it fits into the same UV workflow. If you're on a version within that range, the add-on is built to run there. For versions outside the listed range, check the developer's documentation page to confirm current compatibility before installing, since supported versions can shift as new Blender releases arrive.
Checker applies its checker textures through a node-based system, which lets you inspect UVs without ruining existing materials or adding new ones to the model. The Zen UV Checkers themselves come as specially designed color and monochrome sets that are built to read well, and they're offered in different texture sizes so you can pick the density that suits the mesh you're checking. That approach keeps the model's shading intact while you review its UVs.
Checker lets you add your own checker texture, or even bring in a whole texture library, alongside the included Zen UV Checkers. It also includes a Filter Resolution System for sorting existing textures by resolution and by square or rectangular format, which helps you locate the pattern you want. A UV Maps Properties Tab gives quick access to UV map management, and the interface centers on a multifunctional main menu. Documentation is available on the developer's page for setup details.
Checker is listed as free here in our catalog. Licensing and any current pricing can change over time, so for the most up-to-date terms it's best to check the developer's page directly. The add-on is released under the GPL license and is part of the Zen UV add-on. A demo video is also available if you want to see more before adding it to your Blender setup.
