Func_Illusionary
In this tutorial I will tell you how to apply a func_illusionary brush into your map to be used as a light source.
First of all, what is a func_illusionary entity and what deos it do? A func_illusionary is an invisible brush that is textured on one side with a light texture to emit light in your map. It is only visible in hammer, and in-game the player would never know its even there. We can always use regular light entities, but how about somethign more complex? This is one of the effects func_illusionary can give off.
1. Make a room, and place an info_player_spawn in one of the corners, like so:
2. Make a brush right below the ceiling of our room. 80x60x2 is a good size. Make sure to cover all the sides with the nodraw texture.
3. After that, open up the texture browser and type in "lights" without quotes. You'll see some that look like ordinary textures, while other are white squares. Most of the textures that came up give off their own light, with unique color and brightness.
The texture we are going to be using is "lights/white001". double click it and apply it to the bottom side of the sqaure we made. So far, it should look like this:
4. Select the brush, right-click on it, and click tie-to-entity. Finally, make it func_illusionary. You'll now see a bunch of keyvalues, the only one we need to change is "render mode". click it and choose "dont render" at the bottom of the list. Press apply, then exit.
5. save, compile, and you should see something like this in-game:
An invisible but still fantastic looking light source. You can always play around with the other light textures to get other effects.
