Blueprint sharing is a feature in Spaceflight Simulator that allows you to share rocket blueprints with everyone who has the link to them.
[]
After building a rocket, go to the menu in the building screen, and press "Share". It may take a while to upload the rocket to the sharing server. After uploading the blueprint, select the app you want your rocket to be shared, or copy the link.
When downloading a blueprint, click the link that will lead you to a website that will open the game. Select the world you want the blueprint to be downloaded, and click "Download" when entering the build area. The game will download the rocket in a few seconds.
Errors[]
Sometimes, when sharing a blueprint, several errors might pop up.
No parts in the rocket[]
If there are no parts in a rocket, the message "ERROR: Cannot upload an empty blueprint" appears. Get at least 1 part on a rocket to fix this error.
Failing to download/upload the rocket[]
Sometimes, there's a mistake during the uploading/downloading of the rocket. Try to restart the game if the error is displayed. Another likely reason could be sharing server downtime.

This error may be the cause of poor/no Internet connection. Try to restart the game or connect to an Internet connection.
History[]
This feature was added initially in the 1.35 update. In 1.4 it was removed — When pressing the button, it will say that it is being reworked. Nobody heard about this feature for around 3 years until the 1.5.5 update was released, adding blueprint sharing again. Unfortunately, in that same update, Stef secretly removed the sharing of ".bp files"
