New UVPackmaster Release


glukoz writes:

It's been a month since the first release of the UVPackmaster add-on. It immediately gained a lot of popularity among the Blender users. Despite that developers didn't want to relax their efforts :) They have been working very hard to improve the add-on and today you will notice that a lot has changed since the first version.

Features which were added:

  • support for non-squared textures
  • adding islands to an existing packing
  • improved island topology analysis

But what is more important: the entire packing algorithm was refactored and as a result it is many times faster now in compare with the early release. Good information is that many improvements were incorporated to the free version of the add-on.

Developers have prepared a new video presenting recent changes - see below.

You can get the add-on here.


  1. Maybe I am doing something wrong but a few quick tests (sphere, suzane etc) with the basic version gave me worse results than the default packing.

  2. Are you accounting for texel density? I ask because it seems that texel density is a topic that most people are not focusing on but it is why in particular games look good and perform well. For instance, I mention it because with smaller details captured by small islands in the UV space, it is common to scale those up from the projects standard texel density in order to obtain more detail in those portions of the mesh texture IF decals combined with excluding channel information are not being used to create detail. Would I be able to optimize texel density by scaling portions of the UV and then execute this tool without losing that work?
