Hi I am simply trying to remove the backfaces from my wireframe. The left one has a wireframe material on it. there is my question: How could i integrate an geometry node with "backfacing" as output so that the backfacing side is ignored by the camera?

The right one has a wireframe modifier on it with unchecked "keep original" and a material index of 1. It has two materials. First one for solids is just transparent. Second one is simply a colour. There as well I wanted to put a geometry info node on the solid onces, so that I can see only the front and make that one transparent.

But I seem to not get it right in this instance, while i could have sworn it was a super easy thing to do.

Could anyone point me to the right way? Better solution? Wireframe with backface culling for rendering. ....

Thanks a lot.

For Eevee: Your node setup is perfect. Make sure to go to material settings and tick "Backface Culling". And right below that check box is Blend Mode. For Eevee transparency to work, you must change Blend Mode from "Opaque" to "Alpha Blend" or something else. enter image description here

If you want to do this in Cycles, you will need this setup: enter image description here

    $\begingroup$ Also i figured, i had the blending mode wrong. Something I would not have looked for ... I need to research it a bit i guess. I did set the blend mode to opaque. But with alpha* it works fine in Evee ;) thanks man. $\endgroup$ – Avion32 Jul 9 '20 at 8:03

    $\begingroup$ Oh yeah Im glad you mentioned that; I forgot to mention the Blend Mode in Eevee must be changed from Opaque and set to Alpha Blend or something else. Will update answer for others. $\endgroup$ – Coby Randal Jul 11 '20 at 14:12
