Yes the mod is rather immature, it started as a gag.
The problem I'm having is the main item is a thrown item, but doesn't render when it is thrown(right clicked).
I am attempting to use RenderSnowball to avoid reinventing the wheel, wrapping it in a lambda for the IRenderFactory "conversion"(I have tried an anonymous IRenderFactory and had the same issue) and registering it in in my ClientProxy during PreInit as instructed by the JavaDoc comment for RenderingRegistry#registerEntityRenderingHandler.
The entity gets constructed, ticks, and performs all its functions, I have confirmed that much.
