Hi! Im trying to make the player translucent when they have a piece of armor equipped. This is what I have in my EventHandler class

 

  @SubscribeEvent
    public void PlayerPrerenderer(RenderPlayerEvent event) {
    	if(cancel == true){

      GL11.glEnable(GL11.GL_BLEND);
      GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
    	}
    	if(cancel == false){
    	}
    }

 

I don't know if the GL stuff is right but anything I do in there does not work. Thanks for the help!

Try enabling / disabling GlStateManager.enableAlpha() in RenderPlayerEvent.Pre. You need to have transparency on the player skin, though. Otherwise you'll either have to set the skin yourself in NetworkPlayeInfo - scheduled on a Thread Pool (manually causing the Thread to sleep for around 10 milliseconds) to add a scheduled task to Minecraft (to set the skin with reflection after the NetworkPlayerInfo instance is created - all this is executed on the EntityJoinWorldEvent). Your second choice would be to somehow enable the transparency on te player skin. I would try messing around with GL first before falling back on skin overriding implementation.
