Light Groups in Arnold 5 (updated)

We have light group AOVs (for Surface shaders) in Arnold 5.
Super easy to use.

This is how you do it:

  1. Create some custom light AOVs (Render Settings -> AOVs -> Add Custom)

  2. Name it like this:
    Use the RGBA_ prefix (or any other built in AOV type like: diffuse_direct_ , sss_indirect_ or anything from the Available AOVs list) and add some custom name to it. This is super important!
    For example: RGBA_lightgrp1, the second one: RGBA_lightgrp2
  3. Select a light and add to a specific light group:
    In the AOV Light Group section -> type in the name of light group without the RGBA_ part. For example: lightgrp2

  4. Do that for every light you have.
    You can add multiple lights to a light group of course.

That’s it.

By the way, I found that the “maximum of 8 different light AOVs are supported” is not true. 🙂 You can use more than 8. Maybe Solid Angle not updated the entire documentation yet.

    1. Hi Jakob,
      Good question. Yes, it is possible.
      You can change the RGBA_ prefix to any other AOV type, like:
      diffuse_direct_
      specular_indirect_
      and so on.
      For example:
      diffuse_direct_lightgrp2
      Cheers, D

  1. Thanks for that! Bit confused by the SA documentation, but now I can stop banging my head on the desk.

    On the way I found that when I made a custom aov and then renamed it in the render settings, the original name remained in the Outliner, but Arnold will ignore this in favour of the new ‘user’ one
