UVPackmaster is a (more) efficient UV packing solution for Blender 3D. The add-on is available in two versions: extended and professional. The differences in the list below: efficient packing algorithm: extended and professional multi-threading support: extended and professional measure area of selected islands: extended and professional check for overlapping islands: extended and professional rotate islands to achieve better packing: extended and professional heuristic search algorithm: extended and professional pack for a non-squared texture: extended and professional pack new islands into an existing packing: extended and professional process self-intersecting UV faces: extended and professional select UV islands of a similar shape: extended and professional lock overlapping islands: professional version only grouping by material: professional version only advanced heuristic algorithm: professional version only UV map validation: professional version only The demo version is available for free. It has all capabilities of the pro version, but the packing result is rendered in a separate window - it is not applied to the UV map. Note the demo version still provides 'Area Measurement' and 'Overlap Check' functionalities, so it still has a practical use. All versions available on Gumroad. Demo also available THERE. Additional features: Detect all UV mapping issues
