Model Builder

Model Builder is a useful tool for creating structures, items, or other things that you wish to load into the game. This is very useful for vehicles and prefab structures, as it allows you to load the object in rather than needing to construct it. It is also useful for creating vehicles, kits, and other things you will want to load into the game

How to use
Once at the Model Builder place page, click the three dots next to the name, and then "Edit". This will open roblox studio. Simply drag parts into the build area to build your creation (be sure to remove them from the folder directory first.)

After you're done building, click "play" or "Run". If done correctly, a notification should pop up instructing you to open the Output window. Do this, and copy the large block of text.

In the Compile script, there are multiple settings and a large list of the "malleability" values of all the parts. The malleability is the maximum volume the part can take up. Edits to these values do not reflect in the actual game, so trying to increase a part's malleability this way does not work. Surpassing the malleability of a part will cause errors in the save, so remember to consult these values regularly and make sure you do not surpass them.

Tips

 * You can (or may need to) use pastebin to host your model's code. This can enable you to load massive models, as the roblox textbox limit is 16,000 characters, which is often surpassed by very large or expensive models. There is also an advanced setting in the Compile script which allows you to automatically post model text to pastebin.
 * To change the material a template loads in as, edit its "SDATA" value to whatever material you wish it to be. (NOTE: Spelling counts!) SDATA is also found under certain customization parts for other purposes, such as antenna IDs, polysilicon modes, and more.
 * It can be useful to save your studio files and/or model text for future use, as you don't want to lose your creations.
 * More parts will make the save longer and more expensive, so try to conserve parts, especially on constructions meant to be cheap and loaded repeatedly, like missiles or small vehicles.
