Scale pupils for 3D Fortnite models! (Blender)

CAUTION: This method works, but needs adjusting for Chapter 4 models in order to work.

Explanation: With this method, you use one mapping node to move the (UV) texture origin to the middle of the eyes. Doing this will let you scale the texture from the middle of the pupil, but will also misplace the whole head texture. That’s why we use another mapping texture to invert the misplaced texture’s “coordinates”, essentially undoing everything about the first mapping node’s misplacing, but keeping the scaling origin. Then we use a carefully placed spherical gradient to determine where the mapping node is allowed to scale. This also prevents the shader from scaling the whole head texture and not just the pupils. The third mapping node (which we set to scale to two on the X axis) is only there because Fortnite head textures are basically 2 UVs areas wide.
