Get Attribute: collisionEventPosition

Menu Path : Operator > Attribute > Get Collision Event Position

The Get Collision Event Position operator returns the the coordinates of the point where the particle hit a surface during the current frame.

To write to the collisionEventPosition attribute, add a Collision Shape Block to your graph and set its Collision Attributes property to Write Punctual Contact Only or Write Always.
