The 2D flowmap node calculates a flow map of water flows, similar to the Flow simulation node.
The vectors are stored in the same way as for a normal map:
To add a 2D flowmap node, right-click in the Graph Editor and select Create Node > Simulation > 2D flowmap or press the keyboard shortcut N2F (Node 2D Flowmap).
Double click on the node to open its parameters:
Use the slider the change the number of iterations.
Below is an example of calculated 2D flowmaps:
You can also convert this vector map to a color map using the Vector map to color map node, which then allows you to apply the color map in the terrain.
Below is an example of a 2D flowmap converted to color maps and applied to the input terrain.
|Number of iterations||Sets the number of iterations of the simulation.|
