"Bounce" can be controlled through bitmaps and shaders→ 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 bitmaps and shaders→ 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 bitmaps and shaders→ textures.
Collider Velocity Factor
...
- accepts any positive value including 0
- is mainly used if the collision between particles and objects turns out too weak
- can be controlled through bitmaps and shaders→ 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".
