-And register it:+We're going to need to register our ''BlockEntityRenderer'', but only for the client.  
 +This wouldn't matter in a single-player setting, since the server runs in the same process as the client.  
 +However, in a multiplayer setting, where the server runs in a different process than the client, the server code 
 +has no concept of a "BlockEntityRenderer", and as a result would not accept registering one.  
 +To run initialization code only for the client, we need to setup a ''client'' entrypoint.   
 + 
 +Create a new class next to your main class that implements ''ClientModInitializer'': 
 +<code java> 
 +public class ExampleModClient implements ClientModInitializer { 
 +    @Override 
 +    public void onInitializeClient() { 
 +        // Here we will put client-only registration code 
 +    } 
 +} 
 +</code> 
 + 
 +Set this class as the ''client'' entrypoint in your ''fabric.mod.json'' (modify the path as needed): 
 +<code javascript "fabric.mod.json"> 
 +"entrypoints": { 
 +    [...] 
 +    "client": [ 
 +      { 
 +        "value": "tutorial.path.to.ExampleModClient" 
 +      } 
 +    ] 
 +}     
 +</code> 
 + 
 +And register the ''BlockEntityRenderer'' in our ClientModInitializer:
 <code java> <code java>
 @Override @Override
-public void onInitialize() { +public void onInitializeClient() {
-    ...+
     BlockEntityRendererRegistry.INSTANCE.register(DemoBlockEntity.class, new MyBlockEntityRenderer());     BlockEntityRendererRegistry.INSTANCE.register(DemoBlockEntity.class, new MyBlockEntityRenderer());
