I'm making an animation of Solar system and shadows of all planets are shown, except Saturns rings which have no shadows¸, although there's no light from the Sun coming to the certain parts of the rings. For Saturns rings I used torus.

enter image description here

But when I position the torus at a certain angle, it's completely dark.

enter image description here

This is torus' node tree.

And this is the node tree for every other planet.

My render engine is Cycles.

What could be the cause?

Thank you!

  • $\begingroup$ Hi, quick question: Do you use Cycles or Eevee? $\endgroup$ – DarkSoul Jan 25 at 16:19

  • $\begingroup$ Did you try delete material so default one is used? Does issue persists? If nobody see issue you should post simplified blend file only with issue part still visible via blend-exchange site $\endgroup$ – vklidu Jan 25 at 20:37
  • $\begingroup$ Could it just be that the torus is tilted towards the sun so the backside of it is completely dark? $\endgroup$ – stphnl329 Jan 25 at 20:53
  • $\begingroup$ @stphnl329 Torus is either completely light on one side of it and completely dark on the other one $\endgroup$ – Dino Gržinić Jan 25 at 21:09

I made a similair setup and it seems to work for me.enter image description here

As you can see, I also made use of a light source and put this inside the Sun sphere. There Are several things you need to check.

1) First of all you need to ensure if your light source has shadows enabled. You can check that out in the next image. Select your light source.

enter image description here

2) If you also decide to have the light source inside your Sun, you need to make sure the shadow of the Sun sphere is disabled as seen in the next image. Select your Sun.

enter image description here

3) Third thing to make sure is that you planet is casting the shadows on the rings. See here:

enter image description here

I've added a copy of the blend file:

Hope this helps!
