Here’s a list of all the shit I need to make for ya’ll people. Also, a place where you can see which place you are if you’ve requested a track, as well as check up on the progress of your track. Plus, you can request a track if I tell you I’m open to requests.
Do PM me if you don’t want the tracks details to be posted publicly.
First tool: onboard footage of a lap around that track. This should give you a clue to the camber, elevation, and the sportiness of corners.
If it isn’t flat, then Google Earth is your friend. Search up the track, then draw a path roughly in the shape of the track layout (check the length of the path to the length of the real circuit). Once you’re done you can click Edit > Show Elevation Profile and BOOM, now you know the elevation of every single point along the track’s length.
