Best practices: avoiding entanglement

Entanglement occurs when an object reaches speeds that are too fast for Sansar to accurately track and accidentally passes through the surface of another object. This can cause unexpected results as Sansar tries to determine how to resolve the situation, and can ultimately impact the performance and stability of the scene.

To reduce the risk of entanglement, avoid conditions that may allow excessive acceleration. For example, try increasing the object's density and friction to allow the object to decelerate over time. Dynamic objects should not have excessive height in their initial state as this causes high acceleration as the object falls.

Note: Setting density or friction to zero (something that is impossible in the real world) can have unpredictable and often undesirable effects. We recommend that you give these settings at least some positive value.
