The Flow Map can be used to create flow data at any point in the graph, rather than relying on an Erosion node output. The Flow map simulates rainfall and water accumulation on the terrain.
There are advantages to both Constant Rainfall options. Average rainfall can be used to highlight stronger flow areas, while Constant rainfall can be used to highlight all flow areas. Combining both can be useful for texture creation.
|Rainfall||The number of rain cycles to calculate. Smaller values create small, detailed flows. Larger values create stronger, wider flows.|
|Primary||Adds primary flow to the output.|
|Secondary||Adds secondary flow to the output.|
|Tertiary||Adds tertiary flow to the output.|
|Quaternary||Adds quaternary flow to the output.|
|Uniform||Applies uniform enhancement to all the flows.|
|All||The enhancement value for all the flows.|
|Primary||The enhancement value for the primary flow.|
|Secondary||The enhancement value for the secondary flow.|
|Tertiary||The enhancement value for the tertiary flow.|
|Quaternary||The enhancment value for the quaternary flow.|
|Quality||The quality of the flow.|
