OK, so we have our empty world lets fill it with the things we need for our 3D Breakout game, but first we need to make that blue sky look more skylike. Just like you did with the engine and the camera add a Firefly Sky to the frame. Don't worry about resizing it or where you put it as it will cover the whole of the inside of your world no matter where it is on the frame.

There are 2 types of sky, a Skydome which uses 1 image and wraps it around a spherical sky, which although looks good has issues when you look straight up or straight down, there is also the second type of sky called a Skybox which uses 6 different images and places you inside a cubed sky which if the images are done correctly you can never tell is a cube.

we will be setting up a skybox today as its by far the most popular and you can download premade skyboxes from many places on the internet mostly for free. we have provided you with one called tropical sunset by Heiko Irrgang, Based on a work at http://93i.de.

To set each side texture of our skybox we need to find the skybox directory which is part of this tutorial and select the correct image for the correct direction
