I'm trying to create something similar to this image's sky-box.

enter image description here

I tried cutting holes into a plane and shining a spotlight through. My attempts end up with the light hitting the ground (which I don't want to happen in the majority of the time, nor where the "god rays" visible in my render image (beginner with volume settings)

There is several ways to get this effect ... but in your example are mixed two light effects. One is vertical lights from stars and second light scattering fromcentral light source. So here are some tips.

SunBeam (postpro)

  • enable Compositor
  • use SunBeam node with high Y value to get effect of light comming from top
  • it depence on image, but sometimes you will need to do a pass for stars if there is some another bright source of light (or for masking reason foreground-background)

Glare (postpro)

similar way is to use Glare node > Streaks > 2

enter image description here

Volumetric

For light scattering

  • add Cube with Principled Volume shader

enter image description here enter image description here

For vertical light rays comming from top you can use Volumetric material, but without connection with stars on sky.

  • use 2D Noise texture node for vertical rays
  • add Areal light on top

  • $\begingroup$ I used the Sun Beams, made two render layers, and now am using alphaover to put them together. BUT the sun beams disappear after the alpha over node. How do I keep the sunbeams when bringing both of the layers together? !Nodes $\endgroup$

  • $\begingroup$ Your node tree works as expected imgur.com/lo1B2AW for me. If you want SunBeams in front imgur.com/Wcc6aKu ... I'm not still sure if the effect should be lens flare or light scatter, it make difference in appearance in space. You would probably need Z-Combine node for more complex merge. Please share a screen with your issue. $\endgroup$
