 It is possible to add models to the game using block model JSON files, but it is also possible to render them through Java code. In this tutorial, we will add a four-sided furnace model to the game. It is possible to add models to the game using block model JSON files, but it is also possible to render them through Java code.

-  * We will register the same model instance under a different name, so we'll make sure the model is only baked once.+
   * We will need a ''ModelTransformation'' that rotates/translates/scales the model depending on its position (in right hand, in left hand, in gui, in item frame, etc...). As we are creating a model for a regular block, we will use the one from "minecraft:block/block" which we will load during model baking.   * We will need a ''ModelTransformation'' that rotates/translates/scales the model depending on its position (in right hand, in left hand, in gui, in item frame, etc...).

 +===== More dynamic rendering =====
 +The ''renderContext'' parameter in ''emitBlockQuads'' and ''emitItemQuads'' contains a ''QuadEmitter'' which you can use to build a model on the fly.
 +<code java>
 +    @Override
 +    public void emitBlockQuads(BlockRenderView blockRenderView, BlockState blockState, BlockPos blockPos, Supplier<Random> supplier, RenderContext renderContext) {
 +        QuadEmitter emitter = renderContext.getEmitter();
 +        /* With this emitter, you can directly append the quads to the chunk model. */
 +    }
