Custom Model Data Viewer
by ModLabs
Custom Model Data Viewer lists items that carry custom model data in one creative tab, so resource pack makers can check their work quickly.
What it does
The mod adds a dedicated creative tab that collects items using the 1.21.4 and later CustomModelDataComponent. It detects items that reference a customModelData string and groups them in one place, saving a search through the standard tabs and several files. It is a Fabric mod, released under the Apache License 2.0 and open source, and it requires Fabric API and Fabric Language Kotlin. Only the client needs it, so servers and players without it are unaffected.
Key features
Dedicated creative tab
Items that use custom model data appear in their own creative tab instead of being spread across the standard tabs.
Automatic detection
Items that reference a customModelData string are found without manual listing, so their models are located directly.
Quick model checks
Resource pack creators can inspect, test and manage custom items from one view, including models such as brown dye entries.
