  • Collision Set Defines which Collections are part of the Collision System.
    • Everything All visible scene objects are part of the Collision System. (Default)
    • Include Collections Only the listed Collections are used.
    • Exclude Collections All except the listed Collections are used.
  • Animated Colliders Collide with animated objects in real-time. When disabled, all objects are baked into a static collision mesh at start, using their initial positions.
  • Ignore Wireframes Don't collide with objects that have their display mode set to 'Wire' or 'Bounds'
  • Full Evaluation Slow but comprehensive: Evaluates the objects considering modifiers, constraints, and other procedural edits. When disabled, only the base mesh data will be used (Faster).
  • Collection Instances Includes Collection Instances in the Collision. This includes Linked Libraries and nested Collections.
  • Samples Collision substeps per frame. The default value is conservative and covers most use cases. When using Animated Colliders, reducing this to 4 or 8 can improve performance without noticeable impact.


Per Object Collision Settings

You can add a custom boolean property named ostep.no_collision to any object. When set to True, it excludes the object from all collision calculations, regardless of collection settings.
