With the latest 1.2 update, the author has added a plethora of new features, improvements, and bug fixes, significantly expanding the add-on's capabilities. Among the highlights of this update, ucupumar has integrated support for Blender 4.1, introduced a brand-new baking denoiser, included custom bake targets for packing multiple channels into a single image, added a new mask type, unveiled the option to bake masks as images, and much more.
On top of that, the release has made Group operations less resource-intensive, sped up the merging of layers/masks of multiple objects with the same material, and ensured that Ucupaint now only utilizes necessary nodes.
