Show Me Your Skin!

Note:

Armor transparency options have been removed as of version 2.0. Armor can still be hidden separately from trims and enchantment glint, but no gradual transparency can be set.

The code for this feature was too brittle for me to maintain with the many changes mojang has been making. I'll properly update the description soon™.

If transparency is important to you, I recommend switching to Armor Hider by zannagh, which maintains this feature on newer versions.

Show Me Your Skin! (the exclamation mark is important) is a client-side mod with
optional server-side support that enables extensive customization of armor
rendering. Every feature is toggleable and designed to be as flexible as possible.

Sliders galore

All the armor hiding options you could ever need, in one intuitive GUI.
Including:

• Individual configuration of each armor piece and elytra/shield:
  • Arbitrary transparency
  • Invisibility
  • Enchant glint hiding
• Server-based syncing of settings
• Player name tag display toggle
• Context-sensitive armor hiding
• Per-player settings overrides

Truly flexible

Below are a few examples of the flexibility this mod offers. You can
fully cater the settings to your preference, and change them on the fly if needed.

Context-sensitive hiding

Armor can be restored to vanilla behavior based on certain conditions,
such as being in combat. This means the armor will be shown for a
configurable amount of seconds after a player is damaged.

Multiplayer support

When the mod is installed on a server, it'll enter "server mode" and any settings
you configure for yourself will be visible in real-time to other players.
Though admins can enforce certain restrictions on what settings are available
if they feel the need for it.

When the mod is only installed on your client however, you'll be able to
configure personal settings for every player on the server. Though these are
only visible to you.
