Unit: How can I correct the rotation of player models in a network game?

How can I correct the rotation of player models in a network game?

I have created a game with the network code.

everything works fine, but when the player appears, the model is on the side.
I've tried turning it into 3ds but the player stays on the side when it appears in the unit.
All other objects attached to the main object remain in a proper orientation.

My question is how to define my model so that it appears as normal and not aside.
