Env_Render A Simple Introduction

This tutorial describes a simple usage of the env_render entity.It can be used to alter the display properties of another entity.
Why would you want do to this?
Its best explained by an example,
Maybe you want to collect an item in your level.The illusion you want to create is of the player collecting this item.How does this happen to you the player? Well when you get close to the item it disappears from the screen so this is where the env_render comes in.It can make this brush entity disappear from your view.So for this example lets assume that you are collecting a keycard off a table.The following is needed to make your keycard vanish when you get close,

• A brush around the area of the keycard.You turn this brush to a triger_once entity.Now give this trigger_once a Target of keycard_vanishing.
• You also turn the keycard into an entity...func_wall will do fine.Give it the Name of Keycard.
• Finally you need an env_render(used to make the keycard disappear).Give this the Name of keycard_vanishing.Now set its render mode to texture and fx amount to 0.

So when the player gets close to this keycard, a trigger_once targets an env_render which in turn makes the keycard disappear.
