Learn how to use Gradient Texturing in Blender 2.9x to texture 3d models. A very efficient way of texturing game assets for mobile devices. Using gradient textures, you can make your 3d assets look so much better than using flat colors, and you can still do it by using a very small texture size!
To create a Gradient Texture, I will be using Affinity Photo. It has a very powerful, easy-to-use, and non-destructive Gradient Tool.
