Urrm, first of all, cool project. You said that the UE4 does not have the physics capability you would like to have. But is it enough for being as good as TDU 1, according to driving physics ? Because this would, at least for me, be all i need, löl . When i think about this here, i imagine a TDU 1 with the basic things that where missing, in it. Lightflares, rain + wipers, being able to leave the car or at least open the doors, for cool parking in freeride, but much more important, lighting details. You know, streetlamps, DIFFERENT light in the windows of buildings, orange cateyereflectors on the streets in tunnels or on the road at night. Streetside reflectors in the plancs sometimes. This also ads feeling of speed to the game. Better variaty in engine sound design. Correct reflections in the carpaint and everything, we know they are moving forward instead of backwards on the car, in the original TDU 1. Yeah all this is possible in the UE4. I would overhaul TDU1 if i would want to learn only, and want a game like TDU 1, like you said. I really would like to have a TDU 1 without the failiures, and better graphics, sounds, etc. instead of another game with other spots. I like that island :-q . And in TDU 2 everything is so cartoonish, plus the driving is worse than in TDU 1. For the sound, i think of a system, where single events are independent designable, like backfires, a keyrattle, or material moving sounds, insects that splash on the frontwindow etc. . There should be s seperate rev sounds system for when the neutral gear is put in, and the most important, for every gear a SPEEDBASED revsystem. Not a revhightsystem. You know, how does the car sound in 4th gear at 100km/h and how does it sound at 200 km/h, can be put in different then, not like in TDU1 one file for the same gear in a rev range. There the 1st gear sounds at lets say 6000 rpm the same like the 4th gear at 6000 rpm, and that is crap. If the 1st gear never reaches the speed like in 4th gear at same rpm, the sound will be different with a speedbased rev system. Of course this would be more work, by the factor of gears. 6 gears, six times more work. But it will be worth it, and i would WANT this more possibilities to do things. Tnx for reading :-q.
