A free mod for Valheim, by MarcoPogo.
Toggleable Transparent Sails is a powerful tool that makes it possible to create unique and dynamic textured sails on your boats. The app allows you to set a configuration that will be dynamically applied to your sails. The process is fully client-side, and it only requires two textures. This makes it a perfect solution for people who want to create and customize their own boats.
The textures can be set on the sails themselves, on the keel, on the rind, or on the hull. It is also possible to set a different texture for each boat, which makes the boats look different.
