I was following this cartoony eye tutorial https://youtu.be/qPwrzqeaZ0U?t=86 but instead of black circle i get this


black gradient comes from left to right. My eye is unwrapped. Nodes look exactly like those from video:


This is how my UV map looks:

So where is the problem?

  • $\begingroup$ The iris is too small and not in the center. To make the shader work the iris must be in the center. Select only the iris on the 3D model so you see only the iris in the UV editor. Then in the UV editor, select the menu entry UV > Pack Islands to scale it up. Alternately, select the front view for the eyeball in the 3D viewport, and UV Unwrap with Project from View (i.sstatic.net/6NoYF.jpg) $\endgroup$

To follow this tutorial, you must U unwrap the iris-area on its own..

.. to center it in the UV texture-space. This part of the eye is being implemented as a separate material, so the mapping of any other faces doesn't matter.
