July 2021: Skyboxes [CLOSED]


Start Date: July 12, 2021
Due Date: July 31, 2021 (by end of day, Pacific Time)


Each entrant is eligible for a payment of up to $350, with a minimum of $100 if the entry meets the minimum standards. The exact payment amount for each entrant will be based on the quality of the entrant’s work.


The goal of this Challenge is to build skyboxes which creators can quickly use in their games. The skybox, which is basically the sky, actually plays an important role in the overall graphical appearance of the game, since it affects not only the sky and lighting but all the objects in the game. A well designed skybox can make the difference between an average looking game, and a great looking game.


Design any type of skybox that you want with the fundamental goal being to make skyboxes that are useful to creators and that look good.

It may help to show your skyboxes in a terrain setting with such elements as mountains, trees, foliage, etc. Such an environment will bring out the effects of the skybox, and its effect on the scene. Be sure to give each of your skyboxes a descriptive name.

Core Editor

In the Core Editor, the main components to create a skybox and associated effects are located at:

  • Art Objects: Sky (Components & Adjustment Volumes)
  • Art Objects: Post Processing

These objects have many properties which can be customized to create unique skybox designs. Use as many elements as you need to create an effective overall appearance.


The next time you play a PC or mobile game, take a look at the skybox and note what makes it special. Visit Twitch or YouTube to see the skyboxes in other games.



  • Create a minimum of 10 sky boxes of your own design.
