• This extension bypasses Blender's default 8-UV limit, allowing you to add and organize as many UV channels as you need for your project. It replaces the standard UV Unwrap panel with a new one, adding buttons to reorder, duplicate, and copy data between UV maps.

• UV Tools 3.3.05 transforms UV workflow in Autodesk 3ds Max (supporting 2018–2026) with specialized utilities that streamline unwrapping, distortion correction, and texture optimization. This essential plugin tackles complex UV challenges through automated tools like Smart Unwrap—generating distortion-free seams based on mesh curvature—and UV Packer, which arranges islands with pixel-perfect precision while preserving texel density. Artists gain real-time feedback via visual diagnostics (stretch heatmaps, distortion vectors) and leverage batch processing to handle multiple objects simultaneously. Version 3.3.05 introduces enhanced Relax Brushes for manual smoothing of stubborn areas, improved Texel Density Matching across assets, and UDIM support for multi-tile workflows. Its non-destructive workflow integrates directly into Max’s UV Editor, allowing quick fixes without disrupting existing mappings—ideal for game assets, VFX models, or architectural visualization. Key features like UV Copy/Paste, Seam Stitching, and Automatic Alignment eliminate tedious manual work, while customizable presets ensure consistency across projects. Designed for texture artists and modelers, UV Tools accelerates production with professional-grade results, reducing unwrap times from hours to minutes.
