Kadimbey You made a beautiful description of what we want. Realistic sounds regardless of whether the vehicle emits less or more noise.
It is a combination of three factors, all the noise that the engine and its components of the vehicle, impacts related to the speed with the terrain and its variations (including internal and external sounds) and the sounds of the environment related to climatic reactions (external).
Vehicles available in the game are old models.
All references I have to the MAN Lion's Coach are robust noises in every way. Probably the 900 would have much less noise than other generations.
The big inconvenience is the absence of a sound system compatible with real vehicles and everything that involves the real experience.
I was forgetting, I prefer some older vehicles precisely because it has this sonic identity more touched on.
This feature is present in several games. OMSI is a great example, the base vehicles and DLCs are mostly focused on old vehicles and the thousands of mods created by the community.
Many people want to experience what they have seen in the past. I don't want to belittle modern vehicles, I like them all because they bring comfort, technologies, elegance and a fantastic design.
Yes, we don't see many simulators being developed on the Unreal Engine platform. I believe that the games are advancing in the best sonorous, see the announcement of the new system of consoles, improvements were mentioned in this sector.
And the UE4 is a modern mechanism in constant evolution and in the long term it wants the best option even if there are difficulties at the moment, but we also have to take into account that TML has few employees and a reduced annual budget in view of the large market that focus on in other genres.
But hope remains alive around the subject now that TML has positioned itself and is analyzing and working in the sound field.
It is good to make it clear which way the games should go in terms of improvements and which should be concentrated. The community is a kind of laboratory, many are active and attentive to mistakes and also to success.
At the moment I have no way to add anything else.
Now is to wait for the right moment when something is implemented to the games.
