Unwrap at light speed
UV Flow aims to make UV unwrapping in Blender fast and, even more shockingly, actually fun. It does this by adding an entirely new active tool to Blender’s toolbar, called Cut UV, which allows you to edit seams with ease.

The controls are intuitive and there is a pre-selection highlight to help you never miss a cut. Simply click to mark seams, double click to mark loops (which stop at other seams!!), click and drag to draw seams, hold alt during any of those actions to clear seams, and double click on faces to select islands.

When UV Flow’s Auto Unwrap is enabled, only the UVs affected by the new seam will be unwrapped. This may seem like a small deal at first but, unlike using Blender’s built in Live Unwrap, you will never lose work by accidentally resetting UV’s you’ve previously straightened or projected.

Work in layers
Did you know that having multiple UV maps can be incredibly helpful, especially for placing decals? In Blender you can only have one set of seams per object, which makes working with multiple maps quite cumbersome. UV Flow, however, allows you to work with seam layers. It automatically stores seam information per UV map so you can work with as many unwraps as you need without any extra clicks.

No seams? No worries
When you unwrap with UV Flow, you can set edges to act as if they were seams based on their angle, bevel, crease, sharp, or freestyle attributes. In some cases, especially for hard surfaces, you can unwrap a whole mesh without placing any seams at all! Or you can create seams based on those attributes to use as a quick starting point for a manual unwrap.

See it in style
UV Flow has its own overlay system that you can customize. You can set seams to be any color, as well as make them thicc and glowy for extra clarity (or just for fun). UV checker textures can be enabled by default, so that one is always applied to the mesh you’re unwrapping without you having to think about it. Even better, the texture is only applied to the selected mesh and the rest of the objects stay in solid view. Every effect is fully cleaned up as soon as you exit the tool.

UVPackmaster is a high-performance, GPU-accelerated UV packing engine primarily used as an add-on for Blender and a plugin for Maya and 3ds Max. It automates the process of arranging UV islands to minimize wasted texture space, significantly speeding up the workflow for 3D modeling, texturing, and game asset creation.  

IMPORTANT: Due to the significant changes in the UV API in Blender 5.0, this version can only be installed in Blender 5.0+. For earlier Blender versions, please use the 1.0.3 release.
