This addon has been designed to help layout your UV layout. It provides tools to layout, adjust texel density, translate and select your UVs efficiently.

The tools help ease the process of UVing highres assets spanning across many UDIMS. Models in VFX often contain hundreds of UDIMs so laying out repeating objects, translating and selecting large of amounts of UDIMS can slow you substantially....until now

Features:

UnStack: This tool is designed to preserve repeating objects UVs and arrange them into a clean layout. The addon will create vertical columns of stacking, and once that reaches capacity, it will shift over horizontally and start packing another column if required. If the number of objects exceed 1 UDIM tile, the addon will continue stacking in the next UDIM. For best results, the objects you are laying out must have similar UV bounding boxes. Controls are provided to dial in the tile/island padding.
Stack: The "Stack" tool brings the UVs back on top of each other so you can more easily make global adjustments if necessary.

-Shift UVs: Allows users to easily shift around large amounts of UDIM tiles while respecting UDIM limits. This is especially handy on large VFX assets which can have hundreds of UDIMS. No more headaches rearranging a large UV layout and having to manually move UDIMS around to fit.

Fill UDIM Selection: This tool allows users to very quickly select the UDIMS. Simply select any component in the UDIMS you want to select and run the tool.

Get/Set Texel Density: A simple tool to sample and set texel density. It allows users to choose a unified scale or individual scale when setting the texel density.
(Second fastest texel density tool along side Zen UV available in blender!)
