Atoms can place agents on different terrains using height field and gravity field.
Basic terrain
- Create and agent group
- Add a grid layout module and set the size attribute to (5, 0, 5 )
- Add a state machine module and set the state attribute to 1
- Create a simple ground with some hills
- Open the height field manager formt he Atoms menu Atoms → Heigh field manager
- Select the terrain mesh
- Press the Add button, in the name field of the dialog set a name, for example put "ground"
- Press the select button to automatically fill the mesh field with the ground path
- Press Ok, close the height field manager and rewind your scene
- Select the agent group
- In the state machine module options, set ground has height field
- Rewind your scene and press play. Atoms will place the agents on the mesh
Since computing the height field si expensive atoms will not update it if you modify the ground mesh. If you modify the mesh open the Hegiht field manager, select the height field form the list then press the right mouse button and choose reload to update the height field
Deformed terrain
- Create and agent group
- Add a grid layout module and set the size attribute to (5, 0, 5 )
- Add a state machine module and set the state attribute to 1
- Create a plane and increase the subdivision to 50 50 and scale to 3000,3000,3000
- Add a wave deformer, set the amplitude to 0.1 and put some keyframe to the offset to animate the deformation
- Open the height field manager formt he Atoms menu Atoms → Heigh field manager
- Select the terrain mesh
- Press the Add button, in the name field of the dialog set a name, for example put "ground"
- Press the select button to automatically fill the mesh field with the ground path
- Check the animated checkbox
- Press Ok, close the height field manager and rewind your scene
- Select the agent group
- In the state machine module options, set ground has height field
- Rewind your scene and press play. Atoms will place the agents on the deformed mesh
