an alternate route for gokarts would be to make them oversized, yes but then just scale up some real life gokart tracks to match
that would be the simplest in the short term. But now with the ability to mod anything we can even modify the sizing of the collision box so that cars could be true to scale
Well... Let's say you made a legit Small Model - Like NON WINGED sprint cars MOD outthere... You can clearly see that Skidmarks don't match the wheels.... That is because we got 110 inch wheel base in NR2003 and the MOD creators probably used properly scaled 80 inch something for Sprint Cars. You can EASILY change the wheelbase in the physics editor to be shorter ... In terms it will ACTUALLY MOVE THE PHYSICS WHEELBASE , as well as it will MOVE the skidmarks to proper locations.... Same with the Width of skidmarks and tires , you can fix those in the physics .... BY ACTUALLY MAKING SMALLER/BIGGER tires , not just visuals.
What bothers me is Collision Box. Do you know anything about it and where it might be ?
Just an overall excitement about modding physics should be enough to get people to do things. But its a slow process to change people's minds about modded EXE's. I mean there are mods out there for any racing game but not NR2003. Modding rFactor using editor or NR2003 is essentially a same thing. I don't know why people are so scared.
