In this guide, you’ll learn how to make a kind of \u201cShape Key\u201d to UV Map, it means, make a shape tween and animate.<\/p>\n

The formula we’ll have is very simple to animate a UV Map. This will work both in EEVEE<\/strong> and in Cycles<\/strong>.

\"\"<\/a><\/p>\nThis guide requires basic knowledge of Blender, textures, Shading Nodes and UV Maps.\n

Let’s pratice!<\/h2>\nTo begin, we’ll use a simple curved mesh, with a pupil’s subdivision and texture modifier. The mesh is already with UV Map applied.<\/p>\n

You should already know that the eye pupil contracts and dilates according to the ambient lighting. But instead of trying to make Shape Keys from the mesh, we’ll do it by UV Map!

Step 1: Add two UV Maps to the mesh.<\/h3>\nThe first thing we’ll need is to add two UV maps<\/strong> to the mesh that will be special for the deformation.<\/p>\n
