The first thing you have to do is subscribe to the skin or model you want to use.
For me, I picked this one, but you can pick any.





Note down the numbers after ?id= in the URL of the workshop item.
This is the ID of the workshop item.
In my case, this was 675102547.

Go to where you installed Steam, then navigate to
steamapps\workshop\content\250820
This is the folder for SteamVR workshop addons.

Find the subfolder with the same number as the ID you noted down from earlier.
If there is no folder with the ID make sure you downloaded the item correctly.

That folder should have another folder inside it that varies depending on which controller or device you are using a model for.


Because I'm editing a Vive controller, it's vr_controller_vive_1_5, but yours might be a bit different.

Open a new explorer window, and navigate to your Steam directory again.
Once you do that, navigate to steamapps\common\SteamVR\resources\rendermodels.


Backup the folder that has the same name as the one in the folder from earlier.

steamapps\workshop\content\250820\workshop ID here.

In my case it's vr_controller_vive_1_5.

Take the folder

steamapps\workshop\content\250820\workshop ID here\folder name
and paste it into

steamapps\common\SteamVR\resources\rendermodels

Make sure to press Replace files.
Open SteamVR and you should now have the new skin or model.

To restore the backup, just take the files from the backup folder and do the same thing, putting it in the steamapps\common\SteamVR\resources\rendermodels folder.
