Hey Araklaj,
I have a couple of questions which can help me narrow down the cause of the issue.
- Can you reproduce this in a blank project using minimal content and simple logic?
- What are the Packaging Settings you are using when you go to package your project?
- Are you making sure the character/controlled spawned in the default startup game is the correct character blueprint you have the footstep sounds applied?
Looking at your screenshot, it is hard to determine what the problem could be, without more information or a simple test project.
Thank you,
