You can acquire the 3 Connections Shader by watching a livestream on the Shanghai-based streaming platform, Bilibili.
Destiny 2 is an adventurous video game that takes place in Sol, a mythic science fiction planet. As a Guardian, you must protect the planet’s last safe city from an intergalactic threat.
Players can customize their characters by applying shaders, which change the color of your character’s gear. One of the shaders you can acquire is 3 Connections, which is extremely rare.
Destiny 2: 3 Connections Shader
The 3 Connections Shader is an extremely rare customization feature that allows players to change the color of their gear pieces to pink, blue, white or black.
This Shader can be procured by watching a live stream of Destiny 2 on the Bilibili website. This Shanghai-based video sharing website functions similarly to the popular streaming platform, Twitch.
There was a 1.91 percent chance that players could obtain the 3 Connections shader if they watched a Destiny 2 live stream on this website. It is unclear whether this shader is still available, as it was part of a Bilibili promotion campaign.
However, players can still attempt to acquire this shader by watching a Destiny 2 live stream on the Bilibili website. Keep in mind that the Bilibili website is Shanghai-based, so you may have to use a translation feature to use the website.

How to acquire 3 Connections
When opening the Bilibili website, you should use a translation feature before creating an account. During the account creation phase, you will be able to link your Bungie account to the website.
Some Destiny2 players revealed on a Reddit thread that they had some trouble linking their accounts and had to complete the process several times before it was successfully linked.
Once you have linked your accounts, you have to find a Destiny 2 live stream.
How long should you watch the stream?
In order to get an item from a live stream, you have to watch a stream for a specific duration of time. Unfortunately, it is unknown how long this time is to ensure that you receive the 3 Connections Shader.
One Destiny 2 player revealed that they watched a stream for 2 hours and did not receive the 3 Connections Shader. It is worth noting that you only have a 1.91 percent chance of receiving the shader, as the shader is extremely rare.
How to apply 3 Connections Shader
Once you have the 3 Connections Shader, you have to apply it to your character. Players have to open the character menu and navigate to an armor piece or weapon.
If you open the details menu, you will be able to use the down directional button to open the cosmetic screen.
You can hover over the small square to open the shader inventory, which should give you the opportunity to choose the 3 Connections shader.
