First of all: fantastic work REIZA! I love it!
There is one thing that can be improved though IMHO, it is the cabin movement.
It felt like my head was glued to the headrest - truck fixed, world moving around.
Watch how it is when you drive in a real car - car moves, world is fixed!
In all my sims I try to adjust that, because the stationary vehicle idea is a leftover of early game development.
Luckily that starts to change now, see Assetto Corsa! And a lot of discussion - and resistance to change - in the sim world.
Here is what I found out to make the cabin movement more natural, a simple change in the FTruck_Cams.cam file:
OrientationRate=(10.000000, 50.000000, 2.000000)
all default values were 999, wich effectively stop all movement.
To show the difference I made two crude vids (don't look at the driving, it is for demonstration
(50% Gforce ingame, 6 40 4 there btw.))
WITH cabin movement:
WITHOUT cabin movement:
A good notion of all this is at the end of the vids when I stopped, see how the cabin rotates - or not - when revving the engine.
It must be carefully tuned but together with the headphysics it could be very convincing and immersive!
I hope REIZA Studios take notice and maybe even can do something with it.
Ofcourse everyone can mod their cam files to see for themselves
cheers
