Well, the only thing that makes me hesitate from driving more trails and dirt roads is the constant bombardement with rocks, dust and sand through the fender, firewall, pedals and my legs right up in my face. Until there is actually a physics based dirt system it would be nice, to just set the dirt visibility in the confinded interior space to zero, so that one can drive offroad without ruining the immersion of an otherwise really really nice experience.
Nice idea in theory but how exactly would you define the interior space in a softbody simulator where everything can flex and deform, and the doors can also open or fall of, and some types of offroad doors would actually allow dirt and dust inside, and the glass could break, and you could be upside down, etc. The only way I can think of something like this could be solved would be ray tracing, and that means lag. Better to just get straight to the physically accurate particles imo.
What if the game displayed the car first and the particles second in the interior view? As in, if the car was drawn over particles, it would prevent them from clipping through the car even though technically they would still be there.
With the way the game handles rendering Z order currently (and sometimes produces random results), I doubt it is possible sadly
The bubble is sphere-shaped and the interior has a much more complex shape, I don't think they would be able to change the shape easily without adding more parameters that would surely cause confusing behavior on mod cars
the only other thing I can think of is if you were to cull the particles (or maybe alter their direction of movement?) if they hit a coltri. even if they keep their velocity, but just get "bounced" off relative to their angle of incidence, they'd bounce around the wheel wells and engine bay, then eventually despawn. it would also make burnouts look a lot better, rather than tire particles generally just spilling out in every which direction.
