Nice little track from the pictures. Have not tried your track yet, but looking at the pictures, why do you have the pit entrance blocked off. I am always looking for tracks like this to make them into go kart circuits for myself. Keep up the good work. From other comment, I will try the track later and see why it doesn't load. I use the Content Manager and have SOL and shaders patches.
Tried the track. For some reason your fast lane and pit lane lines dont show up or work. I created a new fast lane line for myself and did a short race. Also your spectator cameras dont work either, just the cockpit and behind the wheel views.
Making personal changes for myself to do Go Kart Racing on this track: Changing from Drift to Circuit mode racing. I dont do drifting.
Added: I went into the kn5 file and tagged the track surface name to PIT- it has other numbering to the name. and tagged all the kerbs with a name KERB plus other numbering. Then went into the SURFACES file and made three "key" items ROAD, KERB, and PIT so that tractions and FFB work properly.
I removed the fence along the pit area so I could get into the pits correctly. I am playing around with the pit stalls and grid positions so they work properly. Will create a new pit lane line for AI racing and new left and right side lines for the track. May do cameras later on.
Just a little fun project to keep me busy. I do this to allot of other Drifting tracks. They make good Go Kart tracks. take care.
