...
A value of 0.0 creates perfect elasticity, while higher settings make the particles lose appropriate amounts of their energy. The maximum value is 1.0.
"Bounce" can be controlled through → textures.
Sticky
It can be seen as a “glue factor” to make particles stick on the object’s surface. You can use positive (attraction) and negative (repulsion) settings."Sticky" can be controlled through → textures.
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."Roughness" can be controlled through → textures.
Collider Velocity Factor
This parameter is only relevant in conjunction with moving objects. "Collider Velocity Factor"
- accepts any positive value including 0
- is mainly used if the collision between particles and objects turns out too weakcan be controlled through → textures.
Interaction > Distance
With 10, for example, particles within a distance of 10 units (depends on the actual scene scale) from the object's surface will be affected by parameters like "Friction", Bounce", etc. The value is calculated automatically based on "Collision Distance". For manual control uncheck "Auto Interaction Distance".
