@SubscribeEvent
            public void EntityViewRenderEvent(EntityViewRenderEvent.FogDensity event){
                   
                    if(event.entity.isInsideOfMaterial(Material.lava)){
                            event.setCanceled(true);
                            event.density = 0.5f;
                    }
            }

 

The event is getting canceled, but the new density setting it not taking effect.

 

Any help would be appreciated.

Try adding

GL11.glFogi(GL11.GL_FOG_MODE, GL11.GL_EXP);

after you change the event.density.

I'm not sure why, but it works for me.

Thanks Azaka7!! That worked great.  Don't know why it's like that.  If anyone could offer an explanation, feel free.

It is a method named EntityRenderer#setupFog() that does this and it seems like when the event is cancelled all further interactions with Fog are cancelled. This means that GL11.glFogi(); is never called and you have to do it yourself.

 

Note: You may also want to call

                    GL11.glFogf(GL11.GL_FOG_START, whereFogStarts);

                    GL11.glFogf(GL11.GL_FOG_END, whereFogIsAtFullValue);

 

I didn't try it out though and I don't really see what could change except that fog is linearly sampled.... try it out, I guess.

I don't know.  I have a great fog effect for a "Jack and the Beanstalk" mod where as you climb up the beanstalk the fog gets thicker and thicker.  It works without doing anything with GL11.

 

Here is the code I used.  You can try it and go into Creative Mode and just fly up to cloud level (I made the fog get thicker when you got into the clouds).

 

    @SideOnly(Side.CLIENT)
    @SubscribeEvent(priority=EventPriority.NORMAL, receiveCanceled=true)
    public void onEvent(FogDensity event)
    {
        event.density = (float) Math.abs(Math.pow(((event.entity.posY-63)/(255-63)),4));
        event.setCanceled(true); // must be canceled to affect the fog density   		
     }

EntityRenderer#setupFog() is private in 1.11.2

You're replying to a nearly 2 year old thread, 1.11.2 did not exist then.
