[1.12] Entity rendering as white cube

[jonesto95]

So I've been trying to add a race cart with a custom entity model, but the models come in as white cubes with no texture or collision. I've been looking at other tutorials for older versions to try and get this to work, but they lead me to deprecated methods and super constructors that take in more parameters than I can.

 

To begin, in the main mod class's preInit(), I register the entity using ModEntities.registerEntities():

public static void registerEntities()
	{
		registerEntity(EntityRaceCart.class, "race_cart", 64, 20, true);
	}
	
	private static void registerEntity(final Class<? extends Entity> entityClass, final String entityName, final int trackingRange, final int updateFrequency, final boolean sendsVelocityUpdates)
	{
		final ResourceLocation registryName = new ResourceLocation(MourningstarMod.MOD_ID, entityName);
		EntityRegistry.registerModEntity(registryName, entityClass, registryName.toString(), entityID++, MourningstarMod.instance, trackingRange, updateFrequency, sendsVelocityUpdates);
	}

Then in the main class's init() I use the Client proxy's init method to access the RenderingRegistry

@Override public void init()
	{		
		RenderingRegistry.registerEntityRenderingHandler(EntityRaceCart.class, renderManager -> new RenderRaceCart(renderManager));
	}

 

Here are my Entity, Model,  and Render classes for reference. The Render class is based heavily off of the RenderBoat class, as I want my entity to function similarly to a boat.

RenderingRegistry.registerEntityRenderingHandler(Class<T>, IRenderFactory<? super T>) must be called before init. It won't do anything if called in init or later.

[jonesto95]

Changed that, and it didn't like me casting the model as an IMultipassModel, so I fixed that in the Model class. Now I have an empty renderMultipass method in there. (Do I even need to make this a multipass model?)

Now when I right-click the item that spawns the car, nothing shows up.

[jonesto95]

Update

The cube no longer renders (I honestly forget how I managed that one, yay!), but I have since added a collision box that does work. The box takes the shape of the cube that should be there.
I also know the RenderRaceCart.doRender() method is called (and by extension, the ModelRaceCart.render() method as well), but, again, nothing is showing up. I feel something is wrong in these methods...?

[jonesto95]

Got it. The render method in the Model class had a bunch of junk in it that seemed to break the rendering. I just need the body.render, spoiler.render, etc. statements. Only issue is that seemed to break the scaling I had on the model. Now it's just a bit of number-tweaking from there to get it right again.
