On Spline you can create different types of physics simulations, each object can be adjusted to react to gravity and collision forces.
How to add physics to your 3D objects
- Go to Environment settings and enable Physics.
- Select the object(s) and go to the Physics section. The following parameters can be adjusted:
- Enabled - Enable or disable physics.
- Children - By default, all groups behave as single objects. If you want the child objects to behave as single objects, change this parameter to Separate, then select all of the child objects and set the parameters.
- Body Type - By default, all objects are set to Positioned, which means that they will not react to gravity forces unless you change the Body Type to Dynamic.
- After setting an object as Dynamic, the following parameters can be adjusted:
- Weight - Controls the weight of the object, which means that heavier objects will fall faster.
- Gravity Scale - Controls the gravity force of a particular object.
- Friction - Controls the amount of friction on the surface, the less friction you set, the more the object will move on the surface.
- Damping - Increasing this value will make the object fall slower.
- Bounce - Increasing this value will make the object bounce more when it hits a surface.
- Collider - Controls the collision type, setting it to Precise will make the collision slower.
- Translation - Constrains the positional movement based on an axis.
- Rotation - Constrains the angular movement based on an axis.
