.Map :: MoHAA Mapping

Can someone answer me this. I see some tuts that have pics of the different playertypes(their uniforms) when they are maping. When I add player types all I get is a colored block.How do I get radiant to show this?
Also, is compiling a map the only way to see how all your models will look in they game or is there some button I missed in radiant that will preview these things?
thanks!

Uncheck view -> show -> models as bounding boxes
