Well, if you create the entity like this (Look into the CreateEntity function in iCelPlLayer):
playerEntity = pl->CreateEntity("player", bl,
"player_behave",
"pcdefaultcamera",
"pcmesh",
"pclinearmovement",
"pcactormove",
"pccommandinput",
0);
And the entity has the pcmesh property class, it can be displayed, and will be by default I believe. There are methods to hide and show a mesh, so you should look into that if you wish. Really, getting an object to be displayed is trivial.
