I have this sort of sci-fi scene with ambient emission lights. I would like to have a gradient for each of them. Somehow my setup creates a gradient over the entire image rather than localized for each plane that emits. How would I have to change my setup in the node editor to get both emissions upper and lower to have a gradient in Z?

Thank you very much in advance! Marlon

  • $\begingroup$ Hello :). Just to make sure - both your planes are one object? $\endgroup$ Jul 9, 2020 at 11:47
  • $\begingroup$ Hey, they are one object but different planes that I assigned the material to. Would it help to make them different objects? $\endgroup$ Jul 9, 2020 at 11:51

    $\begingroup$ When they're one object, you need to use UV mapping. When they're separate, it'll work right away :). $\endgroup$ Jul 9, 2020 at 11:54
  • $\begingroup$ Yep, that worked, as simple as that. I made it separate objects. Thank you!! ;) $\endgroup$ Jul 9, 2020 at 12:24

Making the planes separate objects was the solution (or working with UVs).
