In this chapter we will learn how to create and optimise textures for Minetest. We will use techniques relevant for pixel art.
You need to be aware that MS Paint does not support transparency. This won’t matter if you’re making textures for the side of nodes, but generally you need transparency for craft items, etc.
GIMP is commonly used in the Minetest community. It has quite a high learning curve as lots of its features are hidden away.
For the most part, you want to manipulate pixels on an individual basis. The tool for this in most editors is the pencil tool.
