Placement Range (New for v. 8.4)

Any prop can be chosen for the placement of other props on upward facing surfaces.

1. Create a new project with a terrain and prop.
   
   Distribution does not work for height map terrains.
2. Launch the Prop Distribution panel.
3. Click the Pick Object button, then click the terrain in the Scene Manager (because a terrain can not be picked from the viewport).
   
   The placement markers will appear.
   
4. Follow the same steps described in the Workflow for Distributing Props section to add props into the candidate pool.
   
5. Click the Deploy Props button to place a prop.
   
6. Click on Range Option > Add, then pick the prop floating in the air.
   
   Placement markers will be scattered on the upward facing surfaces.
   
7. Click the Deploy Props button again. The props in the pool will be placed on the surfaces of the newly added prop.
   
8. You can click on the Generate Placement button repeatedly to get the ideal result for distributing the source props.
   
9. Close the Prop Distribution panel and orbit the camera to observe the results.
