Dynamics Operator Property Editor
Sets the overall accuracy of the rigid body dynamics simulation, as well as the accuracy of collisions.
To display: Choose Modify > Rigid Body > Edit Simulation Properties from the Simulate toolbar, or in the explorer, open the Operators folder for the current rigid body simulation Environment and click the Dynamics Operator icon.
The name of the operator is either physX or ODE (see Choosing a Dynamics Engine in the Dynamics guide), depending on which dynamics engine is currently active.
Simulation Accuracy
For more information, see Setting the Accuracy of Rigid Body Simulations in the Dynamics guide.
Sub steps |
The number of times that the rigid body simulation is evaluated at each frame. Increasing this value can make the simulations more accurate, especially with collisions that involve either fast-moving or complex-shaped rigid bodies. |
Collision Accuracy
Sets the Collision Accuracy for all colliding rigid bodies in the simulation environment. You may want to set the collision accuracy level for fast-moving rigid bodies, or for rigid bodies that use their actual shape as the collision geometry, especially for the ODE dynamics engine.
For more information, see Setting the Accuracy of Collisions in the Dynamics guide.
Adaptive Collisions |
Toggles the usage the Adaptive Level value. This computes collisions more accurately by increasing the number of simulation substeps around the moment that the collisions occur. |
Adaptive Level |
Determines how accurately the dynamics operator solves collisions. Increasing this value make the collisions more accurate. If you increase the Substeps value (above) significantly (such as to 100), make sure to reduce the Adaptive Level value (to 6 or less) because the combination of these two parameters can increase the calculations per frame immensely! |
