I want this model to render like this:

Render1

this is done by using backface culling in eevee rendering.

In cycles, however, it's rendering like this:

Render2

I know there's a node set-up in cycles to recreate backface culling, however it did not work and only made the model look glitchy.

Any help would be nice. For reference, here's the model I am using if anyone would want to experiment with it:

If you don't want to turn off shadows use this setup here:

  • $\begingroup$ That didn't work either unfortunately.... I think I might just be doomed here. $\endgroup$ Nov 23 '20 at 4:50
  • $\begingroup$ I should also add that I've tried this with multiple models that had the backface culling problem and none of the setups worked. Is there an addon to add backface culling to cycles by any chance? $\endgroup$ Nov 23 '20 at 5:41

Using Marux's setup above, but switching the "Is Shadow Ray" to "Is Diffuse Ray" fixed the issue I was dealing with on my personal project, which was tweaking an Inverted Hull outline to work in Cycles.
