All types of rails are by default 2D and they're also floating 1 pixel above the surface of the block beneath them. this pack fixes that by making rails 3D.

Ladders have just about the same problems as rails.

Note:

when using this resource pack, ladders seem to have a darker texture compared to the vanilla texture, but as far as I know this is an issue with Minecraft's lighting system and there is no problem with the 3D model or the texture in this resource pack.

The default background of the player(or horse) charecter in some GUIs(like the inventory) is black and feels inconsistent. This resource pack fixes that by changing the the color of that part of the GUI.

The texture of the other sides of all leaves are not visible through the gaps in the vanilla game. This resource pack fixes this issue by changing the 3D model of leaves.

Note: More Culling will not visualy effect this pack, but enabling "Fast" mode leaves culling might still improve performance.

The holes in some doors and trapdoors don't have a texture inside them, I'll fix that in version 4.0
