This parameter describes the distance between the particles and an object's surface in metres. Good values are around 1% of the object’s largest “Scale” value found under Node Params > Node.
DY Interact distance
With 0.2, for example, particles within a distance 0.2 metres from the object's surface are affected by parameters like "DY Friction", "DY Bounce", etc.
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.
...
- 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.
