PropGon UV Trim is an addon that reverses the traditional trim sheet workflow by generating custom trim layouts based on your existing geometry and UVs. Rather than manually fitting UV islands into pre-made texture boxes, the tool scans selected objects, detects assigned materials, and mathematically builds a tailored trim sheet layout.

The toolset includes features for maintaining texel density, offering real-time evaluation to recommend appropriate texture map sizes based on industry targets. It features optimization tools that merge small divisions to prevent mipmap bleeding when exporting to game engines like Unreal Engine and Unity. For texturing workflows, the addon includes a Substance Designer integration that reads exported layout data to automatically generate mask node graphs. Additional UV management tools include automatic alignent to trim divisions, modal scaling, and standard utilities like quadrification and texel density management.
