[MC-47811] The bottom texture of non-full blocks is flipped vertically

The bottom texture of blocks is flipped vertically.
Likely the same as MC-37106, but they missed it in the fix.
Since the other bug does not mention bottom faces, and it is fixed, while this is not, I though a separate issue was needed.

Edit in 14w07a: Full blocks render the bottom face correctly, though partial blocks (such as end portal frame and enchantment table) still flip the texture.

Edit in 14w11b: Any blocks with models now render correctly, but blocks without a model are incorrectly rendering. Stairs, Enchantment Tables, and some others are still affected.

Edit in 14w17a: The only block I'm still noticing with the problem is the Enchantment Table.

Works as intended. It will not look flipped if you look at it from one angle. But from the rest it will

I don't see how this is intended. The texture is flipped, instead of mapping the same like the sides. Makes bottom textures need to be flipped as well.

if it mapped every side then it would have it flipped at every angle you look at it, then it would cause extreme lag and it wouldn't make any sense.

With the way mapping works, It puts the image on the top, south, and west faces. The bottom, east and north faces get the same image, though when viewing it (which is from the other side) it appears backwards. To fix that the north and east faces are programmed to flip the texture on those faces, but not on the bottom face.

Fixed in 14w07a, and I found out it flipped vertically, not horizontally.

Okay, Partially Fixed, only fixed on full blocks

Jason MacWilliams 2014-02-20T18:58:16Z

I have also observed this with slabs and stairs in 14w08a. But with an odd twist, in my testing it happens with the wood blocks, sandstone, and stone brick, but it does not happen with nether brick, quartz, cobblestone, red bricks.

I also see the flipped texture under wood fences but not cobble/mossy walls.

KnightMiner 2014-02-21T14:44:58Z

Yeah, this is also made weirder when the end portal frame is rotated, since bottom textures now rotate with their model.
Overall one of the oddest bugs with what it affects

I'm not sure which is correct, but slabs, stairs and crafting benches match each other, and wood plank blocks match each other, but the planks vs other blocks don't match.

KnightMiner 2014-03-02T03:17:55Z

It seems that the block model is correct, and all other models, including the "grass" model (grass blocks, crafting tables, furnaces, ect.) are currently incorrect.

The bad thing about the new block models is that UVs automatically rotate with blocks. While most of the time this is desired, sometimes it creates this issue.

You can fix this in the model files by duplicating the models (that usually would be a rotated "variant" version) for every direction and then just changing the UV rotation. However, as someone who just spent hours making sure all of the textures of tops/bottoms of iron bars line up in every configuration, this is a pain.

This is where an "alternateRotation" property would come in handy. For the bottoms of these sort of blocks, which are square, you could add "alternateRotation": 0 ...and the texture would never rotate. For rectangles (like tops/bottoms of iron bars) you could add "alternateRotation": 90 ...and the texture would only be able to be its current rotation (when possible without being incorrect) or rotated by 90 degrees. This would cause the top/bottom textures of N/S to line up and the top/bottom textures of E/W to line up without making more models that you need to rotate the UVs.

Fixed in 14w11b on all blocks with a block model (end portal frame, crafting table, ect.). But not blocks without models (enchantment table, stairs).

Christie N 2014-03-21T23:53:17Z

Actually, if you really want to get technical, it's the blocks with models that are rendering incorrectly. Prior to 1.8, a block's bottom face rendered vertically flipped. The only way to do this in a model file is to flip the texture, then rotate it 180 degrees, which Mojang did not do – so we have inconsistencies.

(This makes it really frustrating for those who use multiple cubes while mapping say, rails)

KnightMiner 2014-03-22T15:29:07Z

The original bug post was that the bottom faces were flipped vertically, and in the new models, that no longer happens

Mojang will now likely adjust the rest to the new block model system and remove all the inconsistencies , fixing this bug completely.

KnightMiner 2014-04-24T16:46:46Z

I think all this is not fixed on is the enchantment table. Might be a few others though.

Fluffy89502 2014-04-29T22:52:49Z

oh i thought u ment all blocks. Whoops
