Footsteps sounds missing

[Plazmater]

Does anybody have a problem with no footsteps sound when testing their custom story?
I really want to know what is a problem.

I can hear crouching and standing up but no walking.

Is there a way to test the map without starting the game?

You can start it from the editor?

Idk what you mean... I simply test my custom story by launching ModLauncher.exe in the game folder.

So ye anybody know how to fix this problem?
It is not really realistic walking without footsteps sounds
