I currently have a spline mesh setup of a wooden fence, and a material trace footstep system set up, but the spline mesh will not make any sound when walking on it. I have ensured that the fence static mesh still makes the sound when placed on its own. I also attempted to use a physical material override node in the spline mesh BP to no avail. I have tried swapping the mesh to different ones as well and none work. Are there any common reasons why spline meshes might prevent the footstep sounds from functioning?
