Adding Models to the Game

Any model can be destroyed for points, but it must be placed into a specific folder. You can even copy and paste objects from other Studio files into the template.

To add objects to the game:

1. Delete any search filters you have at the top of the Explorer.

2. Expand Workspace > Arena > Map. These folders, like HighPoints, are where the code looks for what parts can be destroyed and can count for points.

3. Place buildings and props in the HighPoints, MediumPoints, or LowPoints folder according to how that object is worth when destroyed.
