    This is maybe the best map out there for racing, dev quality detailing all around. So excited to see more stuff added in the future. However, one thing that does bug me (and I have no idea if it's even possible to change) is how slippery the asphalt feels it makes it hard to get good lap times or go flat through some of the faster corners without slamming into the barriers. It is maybe just a skill issue I have, but a more rubbered-in track surface with more grip I feel would be amazing and a great improvement. Also, I know it's a work in progress, but some tire barriers would be amazing at the end of the larger runoff areas.

      I really appreciate the kind words. I am glad that you are enjoying the track!

      Unfortunately, the track surface options are limited to a pre-determined list set by the Beam.NG devs. The asphalt I am using is the grippiest asphalt I can use without using the prepped surface used for drag strips. Using the prepped surface would cause your car to flip on tight turns instead of spin and be even less realistic.

      Good idea, I will work on adding tires to most of the runoff areas. Thanks for the suggestion :D

      EDIT: Found out how to make a custom groundmodel, I am going to make the track surface a bit grippier.

    Good potential as a map/track. Very well decorated; It looks like a track that could exist irl. As a wheel user, the bumpy surface makes my wheel vibrate a ton on the straights. For super track oriented cars, like the Pessima touring car, the bumps make it very hard to brake hard without locking up. Open wheel cars like the Formula Ibishu and F4 are really tough to drive on here. The F4 struggles to make it a lap due to there being some kind of sand material on straightaways. It sometimes hits the sand and slows to a complete stop. But i do think this is a promising track. I think the layout is fun and some of the corners with no bump or sand issues are great to drive on. I'm eager to see the future of this mod

      v0.14 fixes the bump/sand issue! I would love to hear your thoughts on the track after you are able to try it. Thank you for testing!

    Good track, I like how complete the circuit feels already! When you get to the AI pathing, I really hope you do it in a way where it's easy for us to send the sandbox AI around a config without us having to basically redo the road network to keep them on one route. That'd make it one of the premier track mods in the game!
