Creepers Refreshed Resource Pack Wiki & Guide

Yes, Entity Model Features is required to display the custom Creeper shapes and models correctly. Without it, you'll only see texture changes but not the unique 3D designs each variant has.

Use a Name Tag on the Creeper you want to lock—this forces it to display as a specific biome variant instead of changing based on its spawn location. The variant it becomes depends on the biome you're currently in when you apply the tag.

The pack automatically changes each Creeper's appearance to match the biome it spawned in, so a Creeper born in a desert looks sandy while one from a forest looks leafy. This is the core mechanic that makes them camouflaged.

You'd need to visit each biome type to naturally encounter all variants, but using Name Tags in different biomes lets you collect tagged Creepers with each design and keep them in one place for reference.
