Character don't move when replacing mesh

When I replace my chracter from a 4.11 project in 4.15/4.16. The character don’t move with W A S D, he can just jump. But when I reset the old character, it works perfectly. How can I correct it? Please :slight_smile: If you need more info for helping me, ask for it please.

Hey OAXP! I’ll start with a simple solution. Have you double checked your input preferences? They may not have migrated over correctly.

Another option, try refreshing the your cast node, mesh component, and variables. Just delete them and re-connect. They may be storing old references.

Also, what do you mean by reset the old character?

Thanks for your answer, but it don’t work :(. And I mean to put the character(the first character) back.
