please not that with crunching textures to one it is not possible anymore to build working two-sided doors because one side is always swapped. But it is possible to use 2 blocks one after the other to correct the other with the downside to have a door which is two blocks thick = 1m :)

updated all blocks -> changed from 6 individual textures with normal mapping to 1 texture for all 6 sides without normal mapping. This should save a lot of VRAM now!
