Hello.
I thought about a physic property for materials where you would choose the kind of material (water, wood, concrete, grass, etc.). Then, from lists of sounds (i.e. walking sounds for the player kind of list), Leadwerk would play them randomly depending on what materials the player is interacting with and depending on the physic of the material.
I don't know how complicated this would be to add. I know I could try to make a system like that by I think having it natively into Leadwerk would be a good point for Leadwerk.
Thank you and have a nice day.
