What is a voxel? A voxel is just like a pixel but with three dimensions instead of two, and building scenes with them results in a really fun style that has been made popular by things like Lego and Minecraft.
This blender tutorial series will show you how to make the most of that style by speeding up your snapping, converting meshes with the remesh modifier, and adding extra pixel detail on your Blender material through the use of a shader.
