When a → RealWave surface is created RealFlow always adds a “Global interaction” taga → “Object interaction global” tag is always added. This tag establishes the connection between an object and the wave surface, and cannot be removed. By default, all objects in the scene are governed by the tag's adjusted values, but this is not always wanted. RealFlow gives you the abilityto control every object individually and control its influence on the surface. In this scene, three spheres will float down a river-like RealWave surface and create different waves.
The scene setup with a rectangular RealWave surface and three spheres.
...
As mentioned in the introduction, the RealWave surface should have a river-like behaviour. This can be activated with:
RealWave01 > Node Params > RealWave > Downstream > 4.0 (or any other value greater than 0.0)
“Stream angle” defines the direction of the downstream. Here, 0.0 can be used, because the spheres will move from the left to the right (= positive X direction) and this direction represents an angle of 0 degrees.
If you want a higher mesh resolution please decrease “Polygon size”. Good values range between 0.05 07 and 0.02.
Adjusting the Spheres
- Select the first sphere.
- Node Params > Node > Dynamics > Active rigid body
- Node Params > Rigid body > @ mass > 250.0
Node Params > RealWave > Interaction Wave > Object interaction01
Repeat the steps above
Create and connect the → "Object Interaction" deformers:
- RealWave01 > right-click > Add Wave > Object interaction (3x)
- Under the "Sphere01" node's "Interaction Wave" option choose the first deformer.
- Repeat the last step for the remaining spheres, but attach “Object interaction02” to “Sphere02” and “Object interaction03” to “Sphere03”.
Adjusting the “Object Interaction” Tags
- Expand the "Realwave01" node under "Nodes" and click on "Object interaction01"
- Leave the default settings for “Object interaction01”
- Object interaction02 > Node Params > Object interaction > Max height > 0.25
- Object interaction02 > Node Params > Object interaction > Wave speed > 1.5
- Object interaction03 > Node Params > Object interaction > Max height > 0.5
- Object interaction03 > Node Params > Object interaction > Wave speed > 2.0
