The final model for gameengine will be triangulated anyway. There is no problem with triangles in static 3d models for games, but you should choose wisely how your triangles will be arranged in animated models, for example - characters.
hi there, i have been watching and reading a lot about how my model should be in quads, but from what i understood this is too make sub division better and cause no errors. But if i was working on a house for example that i plan to use as a game model, does it matter if not all of it is in quads?
