[Solved] Where to put render code for spheres

[Jummit]

I want to render planets in a space dimension, but don't know where to put the code to do that. Is RenderTickEvent what I want?

I found this pretty helpful, but I don't want it to depend on blocks: http://greyminecraftcoder.blogspot.com/2014/12/the-tessellator-and-worldrenderer-18.html

This is what I have so far:

@Mod.EventBusSubscriber
public class EventHandler {

	@SubscribeEvent
	public static void renderTick(RenderTickEvent event) {
		if (Minecraft.getMinecraft().currentScreen != null) {
			return;
		}
		if (event.phase==Phase.START) {
			// render sphere .obj
		}

}

EDIT:

Turns out RenderTickEvent isn't the right event. Using RenderWorldLastEvent worked.
