I'm stuck in curb hell right now so will take a look at this video a bit later for sure. Once the curbs are done it's clear sailing from there. Not that curbs are hard but I want a certain look where they meet the grass which is a pain to model and match up to the land.There really is no shortage of details for this track. This video even analyses the kerbs at each turn (first five minutes)
No track limits for the Indy race, makes for some amazing racing.
