Short description of error
If a material has a Principled shader with the Subsurface property set non-zero (or the clearcoat property), but is unconnected, then it fails to render correctly.
Exact steps for others to reproduce the error
- Open the file:
- Set the bottom viewport to LookDev or Rendered.
- The sphere appears black or gray, even though it should have a red material.
- In the node tree on the right, set the Subsurface property of the Principled shader to 0 and rotate the viewport (to update it). The material now renders properly, even though no connected nodes have changed.
