Basics of Mipmaps in Unity Part 2! Shaders, Bias, and Texture2DLOD! ✔️ 2021.1 | Game Dev Tutorial
✔️ Works in 2020.3 ➕ 2021.1
Mipmaps are scaled down versions of textures Unity generates which look and perform better when the texture shrinks on the screen. In this video, I wrap up this series on mipmaps by investigating how the renderer chooses which mip level to use and how you can influence this with SampleTexture2DLOD and mipmap biases. I also show how to sample textures outside of the fragment shader stage.
