There are several different ideas related to textures. Some of the concepts I go over include things like mipmapping, anisotropic filtering, texture sample filtering and more. By the end of this episode, you should be able to create a small field of cubes if you've also completed the past few episodes :) Challenges: https://github.com/codingminecraft/MinecraftCloneForYoutube/tree/master/Challenges#episode-4-textures My code: https://github.com/codingminecraft/MinecraftCloneForYoutube/tree/36fb0bb81bfa22014e6586f73aaad3c3e9612d0a NOTE: This is super helpful to print out any OpenGL state errors. It catches a lot of simple bugs.
