Easiest way to do it, is to make an nose art with one random dot, this way the file is saved in bomber crew folder.

After we done that, go to the internet and find a picture, best to not get something to complex.
The size has to be max 128x64 pixels and must be a PNG format.
You can use a program like Paint to resize the picture and in return also turn it into pixel art.
When done you need to name the art:
CustomTexture_a_0.png to take the Custom 1 spot in-game.
CustomTexture_a_1.png for the Custom 2 spot in-game.
CustomTexture_a_2.png for the Custom 3 spot in-game.
Ect.

Now go to C:\Users\''your username''\AppData\LocalLow\Runner Duck\Space Crew and place your nose art work in there, because we made a nose art save before, it will ask us to replace the file, if so accept to replace.

Now you are done, it might take a couple tries to get nice looking art work.
