Model Gap Fix is a client-side mod that attempts to fix MC-73186 gaps in block and item models. It removes texture zooming so model faces use their full texture area. Uninstall it if textures start bleeding onto neighboring blocks.
Available for Forge, Fabric, Quilt, and NeoForge on Minecraft 1.18–1.21.10; the visual fix requires client-side installation.
Rent your own Minecraft server and add Model Gap Fix with one click from the panel, keeping the client installation in place to address those model gaps.
