this is looking quite promising already, some of those environments are really coming together, I really like those volumetrics, D: i have got to play around with that!
have you got any plans for gameplay beyond just racing? is it going to be pure uber-micro low friction racing (a la wipeout)? or considering having a dash of combat centric mechanics like rollcage?
watched a few videos, including your old ship texture customizer, you could do something amazing in UE4 utilizing masks and layered materials, along with all the driveable parameters, looking forward to seeing that!
keep it up
