Here are my other classes that should be helpful.

And I am registering my Renderer through this ClientEventBus class

    public static void clientSetup() {
        
        RenderingRegistry.registerEntityRenderingHandler(EntityTypesInit.TREX.get(), TRexEntityRenderer::new);
        
    }

}
    

And here is my main class.
