Stop adapting your 3D models to rigid TrimSheets. Let the TrimSheet adapt to your model.In the traditional environment art workflow, you spend hours scaling, squashing, and moving UV islands to fit inside pre-made texture boxes—often ruining your Texel Density in the process. PropGon UV Trim v2.1 completely inverts this paradigm. You model freely, click a button, and the addon mathematically builds the perfect TrimSheet around your geometry.Combined with our new Substance Designer Importer, you can automate your entire workflow from UV layout to procedural masking in seconds.

What’s New in v2.1 (The Paradigm Shift)

Smart Scan to Trim: Select your objects and hit scan. The addon reads your UV island heights, detects your assigned Blender materials, and automatically generates a custom TrimSheet layout perfectly tailored to your mesh.

AAA Texel Density Assistant: Stop guessing your map sizes. The addon evaluates your mesh’s 3D area in real-time and tells you exactly if you need a 2K, 4K, or 8K map to meet industry standards (Mobile, 3rd Person, or Cinematic).

Anti-Mipmap Bleeding Optimizer: An intelligent filter that automatically merges dangerous micro-divisions (under 32px), ensuring your textures will never break or bleed at a distance in Unreal Engine or Unity.

Substance Designer Bridge: Bake your ID Map in Blender and export a .json data file. Run our included Trim Importer Python script in Substance Designer to automatically generate your entire Color-to-Mask node graph in one click!

Core Features (The UV Toolkit)

Intelligent TrimSheet Management: Effortlessly load existing ID Maps and the addon will automatically generate work regions and divisions for you.

Auto-Align UV Shells: Instant, one-click alignment of UV islands to the nearest Trim divisions, eliminating manual positioning.

Scale & Refit Modal: A unique transformation mode that allows you to scale and “re-snap” your UVs into place in real-time, maintaining perfect alignment.

Essential UV Toolkit: A curated selection of professional tools, including Quadrify UV, Orient to Geometry, and Get/Set Texel Density, ensuring your models are clean before texturing.

Industry-Standard Optimization: Specifically designed for AAA workflows where memory efficiency, texel density consistency, and production speed are critical.

Seamless Integration: Fully optimized for Blender 3.0 to 4.x+, featuring a clean, non-intrusive UI located directly in the UV Editor’s N-panel.
