Been wondering why your car is not running in a very small unit scale centimeters? I've emailed City traffic team about this issue concerning about my cars are not running and they replied back that city traffic is using real world measurements.
what if you're working on a project with a road width of 2.7cm or 7cm or so? Do we have to rescale this roads to a real world scale? that's what I did at the first place but it just got everything mess up.
so Jiseon Kim my friend and a 3d animator, I explained to him the problem and he got a very mathematical solution for this. all you have to do is just go to your Units setup in 3ds max (Customize>Units Setup).
NOTE:THIS PROBLEM ONLY OCCURS IF YOU HAVE EVERYTHING SETUP NOT IN REAL BASE MEASUREMENTS.
Moving on. go to System Unit Setup and change the System Unit Scale value to 1 unit = 100.0 Centimeters. (see image below).
So this will allow you to use the real scale dimensions even if you use cm measurements, in example you have a 2.5cm road.. 3ds max will calculate it to 250cm road.~~~ enough with the math though, get back to work and try it yourself. thanks for viewing my blog. :)
