Deploying Actors on NavMesh (New for v. 8.4)

Use the Crowd Generator to place actors onto a NavMesh.

Deploying Random Actors on the NavMesh

1. Create a new project, in this case, a project composed of a plane and other multiple props.
   
   Keep in mind that height map terrains do not support crowd generation.
2. Create NavMesh based on the props in the scene.
   
3. Launch the Crowd Generator panel.
4. Choose the Pick Object radio button, click the Pick Object button, then click the NavMesh Controller in the viewport or Scene Manager.
   
   Placement markers will appear.
   
   
5. Set the Generation Type to Random.
   
   
6. Adjust the settings in the Options section. For more information, see Generation Type and Option setting.
   
7. Follow the same steps under Workflow for Distributing Actors to place candidates from the actor pool.
   
8. Add motion or iMD files into the motion pool. Suitable motions and iMDs will be picked based on tags on the actors. In this case, iMD files are applied because the actors are to wander the scene.
   
9. Click the Deploy Actors button to place characters onto the markers.
   
10. You can change the displacements density and pattern by editing the Generation Type and Option settings.Note:

    Click the Generate Placement button repeatedly for the ideal permutation.

11. Close the Crowd Generator panel and enter the Motion Director mode to playback the animations.
    

Deploy Actors in Formation on NavMesh

1. Create a NavMesh in the project.
   
2. Launch the Prop Distribution panel.
3. Choose the range by picking the NavMesh. In this case, you can either pick the NavMesh as the target for deploying the actors or use the Volume Controller of the Crowd Generator.
   • Pick NavMesh Only: By picking the NavMesh as the range, you can only deploy actors in Random type (the Formation radio button will be disabled).
     
     The entire NavMesh will be taken as the range for deployment.
     
   • Volume Controller: By using the volume controller, you can deploy actors in random positions or in formation.
     
     The deployment range will reside in the volume.

4. Adjust the settings in the Options section. For more information, see Generation Type and Option setting.
   
5. Add the desired actors into the candidate pool. These actors will be sourced for deployment.
   
   For more information, see Distribution Pool Adjustments.
6. Add motion or iMD files into the motion pool. Suitable motions and iMDs will be randomly picked based on the tags applied to the actors. In this case, motion files are applied since there is no need for the actors to move around the scene.
   
   Refer to the following sections for more information:
   • Repeat and Loop
   • Random Start Frame
   • Combination and Blend Frames
7. Click the Deploy Actors button to place characters onto the markers.
   
   You can playback to playback the motions, change the settings in the panel and deploy again until you are satisfied.Note:

   Click the Generate Placement button repeatedly for the ideal permutation.

8. Close the Crowd Generator panel and playback to view the crowd animation.
