Trim Fix
This resource pack solves the problem of missing armor trim textures from version 1.20 that display incorrectly on 1.19.4 clients. The pack also adds the updated sentry and dune trim textures from Minecraft 1.20 to older game versions.
For the main functionality of the pack, a compatible mod like ViaFabric or ViaVersion is required, which enables connection to Minecraft 1.20 servers from outdated client versions.
Without such compatibility mods, trims will still display with texture errors, however the updated versions of sentry and dune textures will work independently of the presence of compatible software.
