Free models are models created by the community for other users to get and use in games. However, many veteran users dislike the use of free models because it discourages creativity or effort in one's games and many contain scripts that can destroy a player's game. However, they are encouraged by Roblox staff, as they are very useful for game creators who are not so great at building or scripting.
Models can be bought for free in the "models" section of the library. Accessories bought by the player are also treated as models and can be used in Roblox Studio.
Using free models
Models can be bought from the library/catalog, as stated above. However, free models are not required to be bought from the catalog. In Roblox Studio, all models that are on-sale can be used without actually owning them. However, there is a tab in the toolbox where owned models can be used.
Originally, games were also able to spawn free models from the catalog. However, this feature was later removed, likely due to the potential for exploits.
Some free models are known to contain malicious scripts that clutter the workspace, lag the game, and/or even open backdoors for malicious players. For this reason, many users stay away from free models. A good way to make sure a model doesn't have an infection script is to check all the parts of the model in Roblox Studio (by clicking the small arrow next to the model in the Explorer tab), if it is a model that doesn't need any scripts in it, a user can run a command in the command line to remove all scripts, or if it is a model that does require scripts, users can use an antivirus plugin (although they must make sure to only use ones that are safe and verified). Most are found in the form of a weld and the name is often something obvious to its intention, such as "u got pwnd". These kinds of scripts date back to 2008. Other names include: "ERoblocker", "dåååååååång..............you got owned", "Script........... or is it", "Guest Talk Script", "Anti-Lag", "Infection", "4D Being", "Vaccine", "ROFL", "virus" "H75", "OwO PILLA VIRUS OwO", "RED ROBIN YUMMMMMMMM", "MMMMMM PIZZZA UM NUM UM NUM", "I will show your password [redacted]", "ProperGråmmerNeededInPhilosiphalLocations;insertNoobHere" and "IAmHereToHelpYourPlace" just to name a few. Copied models always tend to have a virus in the model.
Endorsed models are models that are officially selected by Roblox staff. They follow specific criteria, such as being able to run without any bugs, errors, or lag, being easy to edit, being able to run independently without having to load other models or modules, and high-quality. The developers who publish these modules receive Robux as commemoration for their work, and their models are typically displayed before others in Roblox Studio's toolbox. Roblox typically endorses models that are made by well established developers, the most prominent ones including Quenty , UristMcSparks , and NWSpacek .
Endorsed Models do not include viruses meaning they are safe to use, however they are still disliked by the Roblox community. When a developer gets official endorsement on one of their models by Roblox, they receive the 'Official Model Maker' badge.
Despite multiple occasions of Roblox encouraging the use of free models, they are often frowned upon by the community. Much of the community believes the use of free models indicates a lack of effort on the creator's part because they used another person's work (and often without giving credit to said person) instead of creating it themselves. Some believe that this shows a lack of creativity and commitment to create a game with fully original assets, which in turn means that they are a bad developer, hence, breaking any trust the end-user may have with their game. Some developers of kits will also sneak a hint box into giver kits that forces a hint that declares thanks to the creator of the kit when deleting the hint creation code, the kit will no longer work, even more confusing is that the code that makes the kit reliant on the hint is well camouflaged. Some models may also create a small text GUI on top of the screen that says the creator of the game thanks the original creator of the model, sometimes even without the creator of the game knowing it.
- There have been multiple instances of users being able to sell free models for Robux. The users who sold these models were banned soon after.
- Users can use free models if they are not so great at scripting. However, it is encouraged to give credit to the creators of the model by listing their names in the description or in the game itself.
- Most old Models have been deleted.
- Many old Models, especially ones with scripts, have been broken due to Roblox updates.
- Users often steal other models and publish them under their own name.
- Users can make a thumbnail for a free model by copying the camera, pasting it to a model then changing the name of the camera in the model to "ThumbnailCamera".
- Many developers of kits will put a hint in the script of their kits that gives thanks to the creator of the kits.
- Whenever a user removes the line of code that creates the hint, the whole model(kit) will stop working completely. It is almost impossible to fix this problem without recreating the hint because there is almost no code that refers to the hint and output doesn't put out any errors neither.
- Some humanoid free models lost their clothing due to their clothing templates being deleted.
- Back in 2011–2013, whenever users published a model, the name would be automatically set to "Model (number here)". It was still possible to change the model name even if the name was set to this. This naming system has been removed since then.
