Making a Collision Object
Defining a Collision Object
A collision object serves as an invisible barrier inside a scene that forestalls different objects from passing by way of it. They play an important function in simulations, animations, and interactive environments to outline boundaries and management object motion.
Making a Collision Object in C4D
To create a collision object in C4D, observe these steps:
-
Create a Null Object: Start by making a Null object within the Scene Supervisor. Null objects act as placeholders or anchors and are sometimes used to manage the place and rotation of different objects.
- Choose "Create" > "Null Object" from the menu.
- Title the item "Collision Object" or one thing descriptive for simple identification.
