Look up "UNUSED" for some variations of textures in the pack, like one that removes cherries from cake.

Emissive elements (nether fungi, respawn anchor, command blocks, calibrated sculk sensor, end portal frame, and especially brewing stand) may cause performance issues when used in insane bulk. I optimized them all I could (without compromising the visuals), but you may crash the game if you are in the proximity of 32,000 armor stands or 352,000 fungi. 
None of these preform worse than a chest.

If you are unhappy with some changes in this pack you can communicate with me on Discord and I can make a custom pack with specific features removed for you.

You can also suggest ideas for the pack on my Discord or StrawPage.
