How to add gradient map to Blender area light? I would like to have area lights with linear or circular gradient, so that the light is more realistic without sharp edges and constant brightness. But as soon as add a mapping node it becomes completely dark (as the bottom image). Is there any way I can add a gradient map on area light?
(I know it can be done with geometry light with emission shader, or a HDR map can be added to an area light - but I am looking for a solution where I can control area light with procedural shader/without an image)
Bonus setup for caustics using normal:
