Gather offers two ways to customize your Space: the Build tool and the Mapmaker. As the creator of a Space, you can use either method to customize your Map and the objects in it. The in-Space Build tool lets you quickly add or delete objects in your Space, while the Mapmaker is a robust editing tool that opens in a new tab and lets you manage everything from the walls and floors to portals and spawn points.
Note: Check out the Space Design section of the user guide for complete details on how to customize every part of your Space!
Build Tool
The Build tool allows you to quickly add or remove objects in a Space, as well as access the Mapmaker and upload custom objects. Just click Build (hammer icon) in the Left Nav Menu. The Build panel opens, allowing you to easily search for objects, quickly add a suggested object (like Draw Battle!), open the Object Picker, upload your own custom image, or access the Mapmaker.
Click Build in the Left Nav Menu to quickly add or manage objects in your Space.
When you've found the object you wish to place, just click anywhere on the Map to add it. When you're done placing objects, collapse the Build panel.
Tip: If you want to snap the object to the grid (handy for chairs and furniture), hold the Ctrl/⌘ key when you place the object.
Erase
If you want to remove an object, click the Erase tab in the Build panel. A red square displays as your cursor. Click on the object you wish to erase.
To remove an object, click the Erase tab in the Build panel. Click on the object you wish to remove.
Mapmaker
For more extensive customization of your Space, click Build in the Left Nav Menu, then click Edit in Mapmaker. The Mapmaker opens in a new tab, displaying the top left corner of the Map. 
To open the Mapmaker, select Build in the Left Nav Menu of your Space, then click Edit in Mapmaker. You know you're in Mapmaker if a grid displays on the Map.
From the Mapmaker, you can add, edit, or remove objects, tiles effects, walls, and floors, as well as add and remove Rooms. Remember to click Save before trying to view your changes.
Note: You can review all the features of the Mapmaker in the Space Design section of our help center.
Collaboration
You can control who can customize your Space through the Global Build setting and user roles. With Global Build turned on, any user can use the Build tool. However, they will not have access to the Mapmaker unless they have the user role of Builder or Owner.
Global Build
To manage the Global Build setting, click Settings in the Left Nav Menu. On the Space tab in Settings, click Space Customization. Toggle Global Build on or off.
To allow anyone to add or remove objects in your Space, open Settings. Click the Space tab and select Space Customization. Toggle Global Build on.
By default, Global Build is turned off. When a user who does not have the Builder or Owner role clicks Build in the Left Nav Menu with Global Build turned off, they cannot access the Object Picker or the Mapmaker.
When Global Build is turned off, a user who is not a Builder or Owner cannot access any options when they click Build in the Left Nav Menu.
User Roles
If you want to allow someone to customize the Space using the Mapmaker, you can add them as a Builder or Owner. Open Settings and select User Roles in the Space tab. Enter their email address and click Add.
To add someone as a Builder or Owner, open Settings. From the Space tab, select User Roles. Enter the user's email address and select Add.
Builders and Owners can access the Mapmaker and use the in-Space Build tool. However, it's important to make sure multiple people are not in the Mapmaker at the same time because changes can be overwritten.
Warning: Only one person should be editing the Mapmaker at a time. If multiple people are editing the Mapmaker at the same time, changes can be overwritten.
