-> You need to change it to `1.12.0` manually.

+# Model Packer
+
+This is new way to convert model
+- Firstly, install [packer plugin](https://github.com/GeyserExtensionists/GeyserModelEngineBlockbenchPacker) for your blockbench.
+- Then, open your bbmodel, go `File -> Export -> Export GeyserModelEngine Model`, you will get a zip, just unzip it to `input` folder.
+
 # Tips
 
 * Pay attention! The pack only regenerates when the number of models changes, you can technically speaking remove the generated_pack folder to force a reload aswell.
 * You do not have to manually put the pack into the packs folder of Geyser, the extension is capable of loading the pack itself.
+* Choose a right texture when use the packer.
 
 # Current issues
 
-* Multi-textures are not supported
+* Multi-textures and Animated textures need use [a blockbench plugin] (https://github.com/GeyserExtensionists/GeyserModelEngineBlockbenchPacker) to export
+
 * Please report any bugs
