- 2. Automatic mode starts after 30 seconds without user inputs or using YAutomatic mode Camera Follow the helicopter from the island to the platform( 1 m 50)Camera orbits around the platform then follow the current operator ( 40 s )Pressing the Y button , will skip to the next stepCamera switches between different fixed point of view with a text highlighting the different effects( 10s per effect x 5 )Pressing the Y button , will skip to the next step
- 3. Interaction mode ( B to change between each camera ) ORBITControl the orbit camera around the platformThe demo is made to be control with an X360 controller
