This technically isn't a rendering bug, but the schematic loading code; I think. The textures themselves are the correct way around (the pumpkin is an easy way to see this).

Unrelated, I think there is a bug in rendering stairs because the textures for the moss stair don't match up at all.

[me4502]

This isn't related to the schematic loading, it's all correct - I believe the issue here is that the world space used by BabylonJS and other 3D libraries doesn't actually match the world space of Minecraft, as it uses an inverted axis. Would have to dive deep into BabylonJS to see if the actual world space can be modified, or to update absolutely everything (including all models etc) that might refer to directions

I've tried just flipping the direction that the blocks are applied, but all blocks with direction-specific rotation such as torches, fences, etc will end up attached to the wrong blocks on the north/south axis
