Free Camera is a commonly used third-person perspective camera in the digital twin scene, which can help users immerse themselves in the virtual scene and observe and understand the objects and structures in the scene from different angles and positions.
In Wings Engine, the roaming perspective of the free camera can be set by adding path animation.
After adding a free camera, you need to add a path animation to set the roaming route.
The effect of the path animation setting is as follows:
You can set animation effects such as play, loop, speed, etc. in the style on the right.
