To speed up the solution time: 1 Under Save every Nth Key, set the Positions and Rotations parameters to a higher number, such as 5. This causes the simulation to set delegate keyframes every five frames rather than at every frame. 2 Increase the Solve rollout > Display During Solve group > Frequency setting to a higher number, such as 100 . This will cause the display to update with the new delegate locations only every 100 frames. To troubleshoot the simulation: In a crowd simulation, it is not uncommon for a short portion of the animation to have a unique problem that doesn't appear on other frames. Use Step Solve to analyze short portions of your simulation when things don't go as expected. 1 Move the time slider to the frame at which you want to start solving one frame at a time. 2 Click Step Solve. To use the keyboard shortcut for the Step Solve button, turn on the Keyboard Shortcut Override Toggle and then press the T key to run a solution in step mode. You can start at any frame. Zoom in to examine the vectors of misbehaving delegates. 3 Press the spacebar to solve the simulation one frame at a time. 4 Press Esc to exit Step Solve mode. Linking Objects to Delegates You can link objects or bipeds to delegates to make them follow the simulated animation. You can link objects to delegates with 3ds Max linking. Alternatively, the crowd system has a tool for automatically aligning and linking objects with delegates. Linking Objects to Delegates | 4787
