PolyUnwrapper is a set of professional tools for 3ds Max, developed by PolyTools3D for texture artists working in the architectural and game industries. It brings together features aimed at improving the unwrapping workflow inside the program.
The toolset includes Multi Stitch for stitching multiple shells at once, a custom packing algorithm with related tools, and a tool for matching shell width and height. Easy grid spacing, a Cycle Checker map, and rendering for UV tiles (UDIM) and open edges round out the set. The PolyUnwrapper toolbar stays on top of the Unwrap Editor.
Version 4.7.0 supports 3ds Max 2016 through 2027 and was last updated in April 2026. It ranks among the entries in the ScriptSpot library and is listed here as free; check the developer's page at polytools3d.com for current licensing.
