it depends on how you load the models, and what kind of material the model
uses. some models use materials that are meant for misc_gamemodels and
generally are vertex lit, while other models such as the bunks should be
loaded as misc_models.
misc_models are static models that are compiled into the map, and their
materials ( shaders ) are lit by the lightmap.
misc_gamemodels are models that are added at run-time, once the game
loads the map, it loads those models. they are not compiled into the map and
therefore are not lit by the lightmap, but receive lighting based on vertex’s.
i had a problem before like this, when i loaded one of the tank models as a
misc_model, it wouldnt show in game.
so if you want to use the bunk models, make shure you load them as
misc_model and not misc_gamemodel.
