If the quality of that version is good enough, then there's no need for me to continue work on this track.




This is a "tech demo" (even though this technology has been around and used for a while) of a totally new version of Pittsburgh International Race Complex. This will serve as my first public release of a track for Assetto Corsa, and the track will gradually improve over time as I receive feedback and my skills improve. A few assets have already been made for this track, but I have not inserted them as they are not needed yet.

The track is completely devoid of anything except for a singular loop of tarmac, the start-finish timing gate, and 1 pit box and start spot. More will (might) come later.

This track will be built with the aid of an aerial LiDAR scan from 2019. More info on this dataset, including downloads, is available through the US Interagency Elevation Inventory and the US National Map service. The scan's resolution is not listed, but I estimate it to be at 0.8m +/- 0.2m. The vertical accuracy is listed at about 10cm.

What I need right now is to determine the proper smoothing values for the track surface, and I can do that with your help. Let me know in the discussion section (not the reviews) if the track is too rough or smooth, and I'll try tweaking the surface accordingly.

In the process, I'll also add details to the shape of the asphalt, like adding the cut-throughs for the North and South layouts, the two pitlanes, and details like a proper projected UV map, paint lines, curbs, and other things I can add to the surface non-destructively.

The goal of this project is to create a track that at least surpasses https://www.racedepartment.com/downloads/pirc-full-circuit.6682/ in quality and accuracy. I am not related to the author of that version, and this version is not based on, related to, or containing any asset from that version. In fact, the LiDAR data I'm using (2019 Western PA QL2 Lidar) did not exist when that version was created.

Despite being very basic, this model does contain a very basic CSP config file, allowing for GrassFX and RainFX to function. No lights are provided (yet). File is CM drag'n'drop compatible.

This project is not associated with the owners of Pittsburgh International Race Complex and is currently being completed independently, without their assistance or endorsement.

  1. Not the update I promised, but still an evolution

    I went off and did some research projects on Geometry Nodes in Blender, and I discovered some...

Latest reviews

The laser data loos very good almost everywhere. The grass at the right side of turn 17 (easily visible coming out of turn 16) has some clipping, but otherwise the track surface looks great!
I love PIRC and happy that it gets some much needed attention. Please keep up with work on this.
PS I'll be in PIRC at the end of July and will be happy to note any gross differences in the track surface.
