Description

When a Light Function material is applied to a light source, and after using a camera position node and plugging that node into the Emissive Color option there is no light being emitted from the light source.

The user had posted this on the forum as well, and another was able to reproduce the same issue. I was also able to reproduce this.

Steps to Reproduce
  1. Create a Light Function Material.
  2. Plug a Camera Position node into Emissive Color.
  3. Place any Light Source in a scene.
  4. Set it to use the created Light Function.

No light is emitted.
