Footstep SFX blueprint doesn't work

Hi, I’m trying to make dynamic footstep sounds and I found a video about that (Dynamic Footstep System In First Person | No Mesh Or Animations - Unreal Engine 4 Tutorial - YouTube) on YouTube. I did everything on the first video (First Person Footsteps | No Mesh Or Animations - Unreal Engine 4 Tutorial - YouTube) but it didn’t worked and I thought maybe if I do the things on second video it would work but it didn’t. Can you tell me the reason and if it’s possible the solution?

I don’t know rest of the code but your Z is positive… Maybe thats why? You should set it to like -2000 or so to make sure it goes down into the ground…

Also ofc you need to make sure to add the physical material to the ground…

Edit: Here is a very nice tutorial on this Unreal Footstep Sounds on different physical materials I - UE4 TPS #30 - YouTube
