This is what I read about the addition of ppl in gt4
In addition, concerning the explanation regarding "グランツーリスモ 4" "("グランツーリスモ 4 "was produced) 2 years approximately, but three concepts were produced on the center. As for that car and nature (landscape - scenery -) with person. With the former work were just the car and the scenery, but now having produced the new work, that the element, person had missed largely it feels keenly. The car is shown more beautifully by the fact that the person is added ", it started saying.
Concerning the element of this person, when entering into the crowd and the pit which for example crowd in course, in clue, and the opencar which do job you can open the roof and the driver securely does the operation which is adjusted to the movement of the car. In the presentation up-to-date image was released, but "there is about quality it improves still, is long it swayed", that comment was left. You say that as for the movement of this human, when the car "of グランツーリスモ" is moving on the physical engine of automobile control, in the same way, the human body is moved on the physical engine, with the notion that where, as for research of the engine it was begun from 5 years, ago it came to the level which can be introduced at last. But according to Yamanouchi you say that it is the level that "still 10 years it is required to for the completion of technology".
What they said about the pics of the pitcrew and animated crowds
Not only the car expression of the person (the person and the car) latest "グランツーリスモ 4" where power has entered. Which extent it is actualized with the latest version, it is unclear, but you say that the crowd and the like where, at the time of the pit clue works around the car, crowds in course is expressed to real
I believe those are ingame, the car models are the same and the textures aren't really that clear but nice but I guess this is CG aswell
Look at the textures, they are the complete same
But we'll find out when the trail version is released but until I'm proven wrong with offical word I'll believe those are ingame.
