This is a project homepage for 2 converters included in "OMSI Road R2L Converters". It includes a spline converter and crossing converter. Simply 4 steps and <1 minute and your job is nearly done.
Yep, "nearly done" as the traffic light can't be automatically reconfigured, so you have to set those traffic lights yourself afterwards. Also the converter won't re-create the crossing with correct road surface mark, thus you need to use some other method to fix it. That's it.
Please make sure...
