UVR Baker earns a spot in the Blender baking library for tackling a narrow but real problem: merging multiple objects and materials into a single PBR texture set. It's MIT-licensed and covers Blender 4.0 to 5.0 with Cycles and Eevee. Worth knowing up front that it isn't heavily optimized, so bakes can be slow and resource intensive — wait for the bake button to turn gray before assuming anything has gone wrong.
UVR Baker is a Blender add-on from Michael Jared that bakes several objects with different materials onto a single PBR texture set. It targets a specific gap in the Ucupaint workflow, which currently cannot bake multiple objects with different materials to one texture set — a useful step when you design separate parts and want to merge them.
The add-on installs from the N-panel. The workflow is to add a second, non-overlapping UV set to your objects, configure the Source UV and Target UV, then select your objects and bake a single or multi-channel result. Ucupaint must be disabled while baking, because it auto-selects images inside its shader node and can interfere with the bake. A Build PBR Material operator can duplicate your objects into a new collection and joins them.
Recommended settings include power-of-two resolutions such as 1024 or 2048, plus a Bake Type Suffix that auto-names baked images, for example BakedAtlas_Diffuse. Baking is resource intensive; the bake is finished when the button turns from blue to gray. UVR Baker is MIT-licensed, supports Blender 4.0 to 5.0, and works with Cycles and Eevee. A demo video is available.
Uvr Baker is best for blender artists who model separate parts with different materials and need to bake them into one shared PBR texture set, particularly those already working with Ucupaint.
Uvr Baker is completely free to download and use.
UVR Baker lists support for Blender versions 4.0 through 5.0, so it covers recent releases across that range. It relies on Blender's baking through the Cycles and Eevee render engines, so either engine can drive the bake. It's an N-panel add-on installed the normal way. For the exact behaviour on your specific Blender build, the developer's page and the available demo video are the best places to check before you lean on it in a production project.
UVR Baker requires Ucupaint to be disabled while it runs. Ucupaint auto-selects images inside its shader node, which can interfere with baking, so the add-on includes a disable button for this purpose. You turn Ucupaint off, run your bake, then re-enable it afterward. UVR Baker is meant to complement Ucupaint's multi-layered texture painting rather than run alongside it, adding the ability to bake multiple objects with different materials to one texture set.
UVR Baker is an N-panel add-on, so you install it the normal way. The workflow starts by adding a second, non-overlapping UV set to all of your objects, then configuring the Source UV and Target UV inside the add-on. With Ucupaint disabled, you select your objects and bake either a single channel or multiple channels. A Bake Type Suffix option auto-names the output, and the Build PBR Material operator can duplicate your objects into a new collection and join them together.
UVR Baker is not heavily optimized, so baking can be very resource intensive and may look like Blender is hanging. The bake is finished when the bake button turns from blue to gray, so wait for that colour change rather than assuming it has stalled. The developer recommends power-of-two resolutions such as 1024 or 2048, since baking at 4k will probably be very slow. Adding a Bake Type Suffix auto-names your images, for example BakedAtlas_Diffuse, which helps keep multi-channel bakes organised.
UVR Baker is listed as free here in the catalog, and it's released under the MIT license, which is permissive. For current licensing terms and any conditions attached to the latest version, check the developer's page directly, since these details can change over time. The add-on supports Blender 4.0 through 5.0 and works with the Cycles and Eevee render engines. A demo video is also available if you'd like more detail before installing.
