rdTexTools is an Unreal Engine Plugin that provides tools for analyzing and optimizing textures.

Written in C++, this tool is tightly integrated in the UE UI, providing context menu options for bulk editing of textures and a toolbar menu in the Texture editor. The plugin is not needed for your packaged project.

A lot of thought has gone into stream-lining the workflow, many of the options take as little as 2 clicks of the mouse.

rdTexTools provides way more than just resizing and combining textures, it provides ways to analyze and quantify exactly how you can reduce GPU memory usage. The Difference Tool is an excellent example - it gives the ability to see (both graphically and numerically) exactly how different two textures are. A great way to see how much difference your optimizations have made.

The same tool is also extremely useful for creating other things such as hard or soft masks, ramping or zooming up or down the pixel values, applying changes to just masked areas and even pre-multiplying out combinations of maps, such as applying a cavity map to a specular map.

New to version 1.1 is the Noise Tool, from where you can create many different types of noise, including Perlin, Simplex, Worley, Voronoi, RandomWalk, Blobs, Blocks and Bricks.

Version 1.1 also introduces a tool to convert textures to Signed Distance Fields.

With rdTexTools, you will find optimizing your textures much easier and faster - giving you more time to focus on other things.
