Find the skin you want to add a space skybox to. The skins folder for Audiosurf 2 tends to be at 'C:\Program Files (x86)\Steam\steamapps\common\Audiosurf 2\skins'
If you can't find it this way, right click Audiosurf 2 in your steam library, properties, local files, browse local files, skins

Open the folder for your desired skin, and inside it create a new folder called '1'. If you want the skin to pick between multiple skyboxes, simply add more folders that ascend upwards from 1. e.g. '1', '2', '3'...


Now we will set up the code so it builds the skybox from six images as opposed to one. Open the .lua file in the skin folder, and using control+f search for 'skybox'. Replace the existing skybox code with the code I have provided below.


The second '1' in the first line of the code is what you should change to match the amount of skyboxes you want. If you have 3 numbered folders in your skin folder, make this number 3. You get the idea.

Your .lua file should look similar to this:

Don't be overwhelmed. It's very easy to use.
If the website doesn't load, I recommend using firefox.

Pick the settings you want. My personal favourite setup is as follows:


Now keep randomising the seed until you reach a skybox you like.

The most important setting is the resolution, as this will not look nearly as good in anything less than 4k. Also ensure that 'unified texture' is NOT checked as otherwise you won't have six images to download.

Now using the facesheet below, right click on each of the squares of the actual skybox, and name them accordingly. Make sure you add 'sky_' before what the facesheet says. For example the far left box should be saved under the name 'sky_neg_z'.

Once you've downloaded them all, your folder named '1' should look similar to this:



Repeat this process as many times as you wish, just make sure that the folders are in ascending order, and that there are only 6 images per folder. If you give a picture the wrong name, the skybox will not line up and will therefore look bad.

Shoutout to orell12 who came across the website used in this guide. Also a big up to Braamberg who made me realise I was taking this for granted and that it should be shared.

Thanks for reading my guide. I hope you have fun with your new skyboxes! Just be careful with how many you make, or your skin folder might end up using much more storage ;)

If you have any questions, or would like to share an awesome seed you find, please leave a comment.
