This is for almost any minecraft java version.
It is only the blockstates that do this. It really bothered me that default fences aren't automatically like this. All wood fence types get as long as the fence.
I hope you enjoy this resoursepack.
Please report any problems with the resoursepack or any mod support requests. For compatibility with other resource packs you may need to delete the files of the pack in models/block and modify the fence post models in your other pack to fix culling issues. For packs that have change blockstates from vanilla, it may not work without tinkering.
