All 13 skins on the DualSense. Stock is free with an account; the rest are in the vault, $9.99 once, and also fit the DualShock 4 and the Xbox controller.
Each skin is fitted to the shape of the DualSense, so the pattern follows its grips and buttons. The same skins are fitted to the DualShock 4 and the Xbox controller too.
On the DualSense the light colour shows on the strip around the touchpad and on the accents along both grips. With the vault you choose the colour and keep it steady, let it pulse or switch it off.
Stock is free with an account. The rest are part of the vault, $9.99 paid once with nothing to renew.
You can try every skin on this site without one. Using a skin, saving a design and getting your OBS link need you to sign in.
Pick a skin, sign in and copy your overlay link. In OBS, add a Browser Source, paste the link and set it to 800 × 600. If you change the skin later, the same link picks it up within about 12 seconds.
