Cursed pack that converts all blocks(excluding entity-blocks like beds, signs and chests) to pixels of these blocks.
Full sub-chunk(16*16*16 blocks) forms actual texture of block.

Optifine NOT required.
To properly work with optifine you need to switch OFF Video Settings -> Performance... -> Render Regions.
May be compatible with 16*16 texture packs.

Known issues:
Blocks with invisible parts may be not visible at all in some places.
Textures of entity-blocks aren't affected by this pack, because shader can't get.

---

Multisizeable version is compatible with all resolutions texture packs. Textures with my pack are divided by 16 and full texture forms from full sub-chunk.

Optifine NOT required. Optifine influence isn't researched for now.

Known issues(+default):
Some artefacts on borders of some blocks.
Glitchy flowing lava and water.

Credits:
For examples of additional pack are used Depixel, Faithful to Vanilla Minecraft and Textures made of blocks texture packs.
Additional thanks to my friend BananVovan (Bananas Team) for taken screenshots of ↑, because I don't have enough performance for this. (\(;..;)/)

Wanted bugs.
