hi everyone

i have a problem getting my 3d character to work in the lyra starter game. i have followed this tutorial How To Change The Default Characters In Lyra For Unreal Engine 5 - YouTube but when i use my new characters skeletal mesh in the b?manny blueprint class and then launch the lyra game my character is still doing the T POSE

I hope that someone in the community can help me understand what i have failed to do.
