Backface Culling

• I have checked existing feature requests, and my idea is different

Describe the context

In Minecraft some blocks (glass, doors and the nether portal) have backface culling, while Mcprep does not, so I asked why and got this answer. Indeed, it wasn't necessary until Minecraft 1.21.2, in which Mojang changed the redstone torch model, so without backface culling it looks weird.

How do you imagine your feature works?

Add a "Use Backface Culling" bool property to the Prep Materials panel (It should be enabled by default) . So if it's enabled Mcprep will add this node setup to the materials that should have backface culling.

That setup works fine on eevee, eevee next and cycles. It should also work fine on different versions of blender

Edit:
I made a better node setup

What existing workaround (or closest thing to a workaround) do you have today (within Blender, MCprep, or any software)? If there is no workaround, explain why you feel this way.

I'm not sure what you mean by "What existing workaround do you have today ?". Is it like "Is there any existing implementation of that node setup ?"
