NoMansSky:Editing NMS Textures
From Step Mods | Change The Game
Introduction
No Man's Sky uses the .DDS format to store its texture files and they all are located in the TEXTURES folder from the unpacked game assets. Conveniently, they are more or less organized in directories mimic the directories of MODELS folder. This way if you find a 3D model, you can quite easily find the texture and vice versa.
Format itself stores one or more textures, with or without alpha layer. This format is quite well known but still require some plug-in to be read and write by most paint programs. In this tutorial, I will explain how to edit them in Paint.net and in Photoshop.
