How to Add Custom 3D Models (MCModels) to Minecraft Crates

Vanilla chests are cool and all, but if you want players to actually buy keys, your crates need to look premium. Here is how to hook up custom 3D models to your crates.

If you browse the top servers on any server list today, you will notice an immediate trend: vanilla Minecraft blocks are out, and custom 3D assets are in. Players have come to expect high-quality visual experiences, and your Spawn is the first impression they get.

If your crate area is just a row of vanilla Ender Chests and Shulker boxes, you are leaving engagement (and store revenue) on the table. Adding custom 3D models — like floating sci-fi vaults, animated treasure chests, or massive elemental crystals from sites like MCModels — is the meta.

Here is exactly how to link custom resource pack models to your crate plugin in 3 steps.

Step 1: Choose Your Resource Pack Engine

You cannot simply drag a 3D .json model into your Minecraft server files and expect it to magically work. You need a plugin that compiles and forces a server resource pack to the players. In 2026, there are really only three acceptable options:

Nexo — The fastest-growing resource pack engine right now. Clean config format, active development, and great documentation.
ItemsAdder — The veteran of the two. Extremely feature-rich with a massive community and years of tutorials behind it.

Both work by compiling your model and texture files into a server resource pack that gets pushed to players on join. You drop your downloaded model assets into their respective folders, define the item in a config, and the plugin assigns a unique CustomModelData (CMD) tag to make it addressable.

Step 2: Grabbing the Item

Once your resource pack engine has reloaded (e.g., via /nexo reload or /iareload), grab the item in-game. For ItemsAdder use /ia get <id>; for Nexo open the item browser with /nexo items. Place it in your inventory and you are ready for step 3.

Step 3: Linking it to Your Crate Plugin

This is where the process heavily splits depending on the crate plugin you are running.

The Hard Way (Legacy Plugins like Crazy Crates)

To use custom models in older plugins, you have to do some heavy lifting in your configuration files:

Open the physical configuration text file for the specific crate.
Find the BlockType or Item parameter.
Manually specify the exact CustomModelData integer. Because these plugins rarely use real blocks (they use floating items inside ArmorStands), you have to guess and check the XYZ offsets so the 3D model does not clip into the floor.
Reboot the server or reload the plugin to test it. If it floats too high, alter the Y-axis config decimal and try again.

Expect iteration: Getting the offset exactly right typically takes 5–15 reload cycles. Every restart costs server downtime.

The Easy Way (Using Phoenix Crates)

Because Phoenix Crates was designed specifically alongside the rise of custom resource packs, this process is fully integrated.

Take the physical 3D item you got from ItemsAdder or Nexo in your hand.
Open the Phoenix Crates in-game editor by typing /phoenixcrates editor.
Select your crate, and simply click the Set Display Block or Set Key option while holding the item.

Phoenix Crates natively reads the CustomModelData, the NBT tags, and the exact material type. It registers it perfectly, and formats the hologram heights automatically so your 3D chest sits flush on the block. Zero YAML editing, zero server reboots.

A Warning on Model Optimization

Before you go downloading a dozen 3D models for your crates, remember that highly complex models with huge polygon counts will lag your players' FPS (client-side lag) when they sit in spawn.

Always look for models that have been optimized for Minecraft. You want high aesthetic value without making your players with weaker graphics cards lag out when they look at your crates.

Tip: When browsing MCModels or BuiltByBit, look for listings that mention "optimized for Minecraft" or explicitly list a low polygon count. Most quality sellers include this in their product description.
