Animated objects are like Mesh objects with additional properties.
Use an Entity object to add an animated mesh object to a zone. You will assign a Collada (.dae) file that contains animation to the Entity object.
Animations created on the Mixamo website and downloaded as a Collada (.dae) file work.
1. Create a new object Visual-> Entity
2. Set the Resource Locator using the resourcelocator field in the Property Editor (click the Browse button to find the animated .dae file on your disk.)
