This panel is only visible with a → Dyverso domain present in the scene. It governs and controls the interaction between particles and an object.
DY Collision distance
This parameter describes the distance between the particles and an object's surface in metres. RealFlow automatically adjusts “Collision distance” when an object is added or imported, but after scene scale changes it normally has to be corrected. Good values are around 1% of the object’s largest “Scale” value found under Node Params > Node.
DY Friction
A value of 0.0 creates absolutely no friction and a perfectly even surface. Higher values can even stop particles from moving. This parameter accepts all positive values including 0.0.
DY Bounce
A value of 0.0 creates perfect elasticity; higher settings make the particles lose appropriate amounts of their energy; the maximum value is 1.0.
DY Sticky
It can be seen as a “glue factor” to make particles stick on the object’s surface. There are few things you should know:
- You can use positive (attraction) and negative (repulsion) settings.
- Use a value similar to gravity as a reference and then adjust it further.
- This parameter only works with static objects.
DY Roughness
This value ranges between 0.0 and 1.0 and adds randomness to the object’s polygon normals to produce a slightly different collision direction.
DY Interaction Factor
With this parameter it is possible to amplify the object's influence on the Dyverso fluid and create more turbulence. “Interaction factor”
- accepts any positive value including 0
- is a very sensitive parameter and should be altered carefully.
