# Working with a group. Randomization. Camera rotation.

**Group (group)** – a type of object intended to be the parent for objects nested within it.\
Without nested objects it is invisible and meaningless.\
You can set position, rotation and scale properties.\
A group is necessary for convenient management of the objects nested inside it.

You can nest anything in a group, including other groups.\
The exception is the background.

**Two unique functions are implemented in the group:**\
\- randomization;\
\- look at camera.

**Randomization** allows randomly selected objects, groups of objects, or full scenes to be shown each time the project is opened.\
The number of objects that can be implemented in a group with randomization is limited only by the overall weight of the scene. There are no other restrictions.&#x20;

Put into the group what you want to open in the AR layer, check the "Randomization" box and save the project.

**With this functionality you can create simple primitive games, organize giveaways, run promotions and much more.**

*Upon request we can quickly refine the functionality.* \
*For example, set a limit on the occurrence of a single object in the group and more.*&#x20;

**"Look at camera" will allow you to rotate:**\
\- the model's eyes toward the camera;\
\- buttons for convenient pressing;\
\- video, for example, a person with the background removed (a hologram).

The functionality will allow you to create realistic and spectacular projects.
