No model is seen in play

[Dominus15]

I got a model of a very nice naga map and I would like to use it in my custom map, the problem is that in the model editor it can be seen and apparently there is no fault, but when passing the texture and the models both main and portrait are not seen in the game, only the red or blue tips that belong to the texture with team color of the same model are seen, and the rest looks dark or black, I do not know what happens or why it happens, help
