Alpha materials with thickness? (fence material)

Hello fellas,

i would like to create a fence material which has a specific ornament texture on it, which has a alpha mask.

(as you can see her: Fotografie - Bilder und Fotografen | STERN.de)

But i dont want to model all the details because that would cause a huge lack of performance, so i just want to use plane with the texture on it and a alpha material.

The problem is that alpha materials which are used on actors dont have any thickness, so you can easily see that it is just a texture.

I tried using the parallax shading method but that doesn’t work.

If someone could help me i’d be really happy, thank you!

Planes don’t have thickness. Did you try using a cube with overlapping UVs for the sides?
