Sets

Sets were groups of models or decals that were created by players on Roblox. These sets could've been subscribed to, allowing players to easily find needed models in one, easy-to-find location. Sets were located under the Develop page. On this page, you could've seen your sets & subscribed sets. To delete a set, click on "Delete this set". You must have an image for it. To formerly search for sets, go to Subscribed Sets and click Find Set.

Although sets were discontinued, the insert tool is still able to load up all of the sets you were previously subscribed to, as shown below.

How to Add a Model/Decal to a Set
Currently, since the UI updates, the feature to add models to sets is currently disabled. Users found out unofficial ways to add the "Add to set" button back using older versions of the site by changing the Roblox using various plugins.

Trivia

 * There is no set ID 1, the first being 2.
 * Sets ID 2, 3, and 4 were all owned by Roblox.
 * If a model is not a free item, then you cannot add it to a set.
 * If a set you own is deleted by the owner, you will receive a message from Roblox to inform you.
 * If an item is deemed untrusted, it will be removed from the set and owners of the set will receive a message from Roblox telling them so.
 * With the removal of sets trying to access the sets page now redirects to this page
