[1.7.10] Custom particles not rendering

[TehStoneMan]

Hello. I am trying to create a custom blue flame particle, but I am unable to get it to render. My code appears to work, but nothing comes up in game. Can somebody help?

Did you register the particle? I know hardly anything about particles but I know most stuff need to be registered. Correct me if I'm wrong.

[TehStoneMan]

There doesn't seem to be a way to register particles. You almost need to build your own particle system to have custom particles.

The problem is, even though my code seems to be running, having run it through a debug trace, it just doesn't seem to render my particles.

I had this problem too, the thing is that FXLayer 3 doesnt have any render code. So you need to call the draw() methode (and some other opengl stuff) inside your ZombieEntityFX class yourself
