[1.8] New Rendering Methods

I realized that the rendering methods have changed for 1.8, but I cannot figure out how to use them. I have successfully rendered throwable entities first by including a factory in the render class, then registering it in the main mod class using this method: 

RenderingRegistry.registerEntityRenderingHandler(EntityGrenade.class, RenderGrenade.FACTORY);

But I cannot render regular entities. I tried the same methods but with no success, they render as invisible entities.

My render class for the regular entity is here: https://pastebin.com/HtZBA2L1

and the register method I used is as follows: 

RenderingRegistry.registerEntityRenderingHandler(EntityNuke.class, RenderNuke.FACTORY);

So what exactly is the trick to rendering in these newer versions? (Please do not tell me to "upgrade" to later versions)
