# Raycast Mode
* **Mesh Mode:** Targets the actual mesh (geometry) of objects. Offers a high level of precision, ensuring placements align directly with visible surfaces. Ideal for intricate objects where surface details matter.
* **Physics Collider Mode:** Interacts with the collider component, rather than the visible mesh. Faster in performance, especially when dealing with complex objects. Best suited for broad placements or when the visual representation matches the collider shape closely.
* **Both**: Utilizes both mesh colliders and physics colliders, prioritizing the one closest to the Scene View camera.
