FullBlockChests

Turn chests into full blocks and make them openable even with a block above, like before Beta 1.8.

Configuration

A config file is available at config/fullblockchests.properties after first launch. It contains two options:

• reskinModdedChests (default true)
  If false, will only turn vanilla chests, trapped chests and ender chests into full blocks.
  Otherwise, all modded chests derived from the vanilla chest entity will be affected. This means you need a resourcepack to add block and item models to modded chests, otherwise they will appear as black and purple checkerboards in-world, and be invisible in item form.
• disableBlockedCheck (default true)
  If true then chests can always be opened, regardless of any solid block or cat standing on top.

Q&A

Why do chests still make the modern opening/closing sound?

This mod's purpose is to make chests into full blocks, not to customize them further.
Use a resource pack that changes assets/minecraft/sounds/block/chest/*.ogg.

Nostalgic Tweaks does the same thing!

This mod has significant overlap with (and in fact is based on) Nostalgic Tweaks's chest "Eye Candy" tweaks,
but NT limits itself to vanilla chests (see BlockEntityRenderDispatcherMixin
& ChestBlockMixin)
and does not change the behavior of chests covered by a solid block or a cat.

Christmas chest skins don't work anymore!

Yes, I know. Feel free to fork this mod and find a clean way of implementing this with regular block model predicates.
