The upward-facing side is sometimes incorrectly culled

[WinExp]

When I added some of the resource packs, I saw that some of the rail had the upward facing side incorrectly culled when Block State Culling is enabled.

Can you include the resource packs you where using?

[WinExp]

Probably not, this resource pack is a paid resource pack and sharing it requires the author's permission, which I don't have

[WinExp]

I asked the author and he asked that the resource pack not be accessible to anyone else, can I send it to you via email?

[FxMorin]

@WinExp I would rather you send me it on discord if possible. At fx.morin

the cullfaces of the model are set wrongly. basically "cullface": "direction" needs to be removed from elements which shouldn't be culled when that side is culled

[WinExp]

But it looks like vanilla calculates whether the face is actually occluded or overlapping, so if moreculling does the same thing then shouldn't it have this problem?

[FxMorin]

This is kinda true, but not really. Vanilla just culls really inefficiently.
We may look into doing some optimizations for this later, however I wouldnt expect that any time soon.

vanilla just have canOcclude which is false for rails and a lot of other blocks. this is what happens if you set it to true for rails
