The direction field module creates a velocity field affecting the agent directions.
The field is uniformly distributed on the surface UVs. Use the "Direction field context tool" (Maya only) to paint the vectors direction. Each agent will look for samples inside the "maxDistance" radius to interpolate the final direction at every frame.
Attributes
| Attributes | Type | Overridable | Description |
|---|---|---|---|
| mesh | mesh | no | Input mesh. Must have valid UVs, since the module generate samples using the UV coords. |
| meshParentMatrix | matrix | no | The mesh parent matrix. |
| meshTranslation | vector3 | no | The mesh translation. |
| meshScale | vector3 | no | The mesh scale. |
| meshRotation | vector3 | no | The mesh rotation. |
| weight | double | yes | Weight. |
| tangentSamples | string | no | Serialized MapMetadata, Contains some UV samples with their direction. |
| debug | bool | no | Enables module debug drawing. |
| resolution | vector2 | no | Number of row and column of the sample grid generated inside the UV space (from 0.0 to 1.0). |
| maxTurnAngle | double | no | The max turn angle. |
| debugVectorScale | double | no | Length of the direction vectors drawn by the module when the debug attribute is on. |
| isAnimated | bool | no | If the input mesh is deformed over the time. |
| useHeightField | bool | no | Use an Height field instead of the input mesh . |
| heightField | string | no | Height field name. |
| influences | int | no | Max number of neighbour samples used by each agent to compute the final direction. |
| maxDistance | double | no | Max search distance |
