I've created custom overlay rendering on entity (just like fire overlay) when entity has potion effect.

My problem is my custom overlay not rendered on other entities but only work with player.

Not sure why it doesn't work  Please let me know if I doing something wrong, Thanks.

    @SubscribeEvent
    public void onRenderLiving(RenderLivingEvent.Post event)
    {
        EntityLivingBase living = event.getEntity();

        System.out.println(living.getActivePotionEffects().contains(MPPotions.INFECTED_CRYSTALLIZE)); // debug test - always return false

        if (living.isPotionActive(MPPotions.INFECTED_CRYSTALLIZE))

I've looking at Twilight Forest render event, Ice Cubed will rendered if entity has slowness attribute.

https://github.com/TeamTwilight/twilightforest/blob/1.11.2/src/main/java/twilightforest/client/TFClientEvents.java#L53-L61

 

So I've try the same way as TW does. (Sorry I'm not expert at custom packet and I really don't understand how to do step by step as you said) But this working correctly.

    private static final AttributeModifier CRYSTALLIZE_POTION_MODIFIER = new AttributeModifier(UUID.fromString("0B0BC323-E263-4EF8-9108-4B6503129B16"), "generic.crystallize_effect", 0, 0);

    @SubscribeEvent
    public void onRenderLiving(RenderLivingEvent.Post event)
    {
        EntityLivingBase living = event.getEntity();
        // check if entity has crystallize potion modifier
        boolean hasPotion = living.getEntityAttribute(InfectedCrystallizeEffect.CRYSTALLIZE_EFFECT) != null ? living.getEntityAttribute(InfectedCrystallizeEffect.CRYSTALLIZE_EFFECT).hasModifier(CRYSTALLIZE_POTION_MODIFIER) : false;

        if (hasPotion)
        {
            GlStateManager.disableLighting();
            TextureMap texturemap = this.mc.getTextureMapBlocks();
            TextureAtlasSprite textureatlassprite = texturemap.getAtlasSprite("moreplanets:blocks/infected_crystallize");
            GlStateManager.pushMatrix();
            GlStateManager.translate((float)event.getX(), (float)event.getY(), (float)event.getZ());
            float f = living.width * 1.4F;
            GlStateManager.scale(f, f, f);

Hm, I found some problem. Not a game breaking, So how I can fix this after reload worlds?
