Ray tracing likely adds complexity. Don't forget that cars that were formerly Standard vehicles in the PS3 era needed to be rebuilt from scratch.
I remember hearing certain outsourced cars would take three months to complete, while nine months is the time frame for individual artists from Polyphony doing all the work in-house.
The fact we got 30 cars in nine months would make me assume there are 30 people on the car modeling team, with each working on one car alone (assuming Polyphony aren't outsourcing anyone at this period).
It could also be assumed that the currently-known cars that are leaked in the datamine have been built for some time and are going under quality control before being released.
Hopefully 2023 will see a much larger volume of cars per update. Something like GT Sport's early days where up to 15 cars were featured in one update, given the world is slowly normalizing.
They're building 60 cars per year currently. This seems to be all in-house, although some work maybe done outside.
――Could you tell us if there is a target number of vehicles included in the GT7?
I can't say anything (laughs). When the "GT" series was at its peak, the number of models included exceeded 1,000. However, at that time, there were some that looked almost the same but differed in grade, so I think that the value of the 1,000 units at that time and the 400 units now are quite different, including the accuracy of the model.
At that time, the interior was only recorded for some cars. Currently, we are developing at a pace of about 5 units per month and about 60 units a year, but I don't think that is such a bad pace.
And not only the car model, but also the interior, the physics of each, the engine sound, etc., are clearly over-spec even with the current PS5. So I don't think we need to remake it again in the future, and I think this will be a cultural legacy. And the car model will be gradually covered.
