I think you finally solved the mystery of which version I have. I must have the Tiago Lima version with the addons, although I disabled the train addons. There were times where the train was there as I crossed the track and I just ghosted right through it. Kind of broke the realism factor when that happened.
I've already started the process of adjusting things for the track. Since there is so many versions out there, is there a particular one that I should be using as the base version? I have the Reworked version looking like the original with regards to the texture detail and color. Like you, I also prefer the higher mountains of the original (just not quite that high). My sweet spot is somewhere between the Reworked mountain height and the original mountain height.
And as a first step in the process, could someone give this updated ai a try. I don't know about anyone else, but the ai for me is struggling on the final turn. Cars missing the turn completely, some ending up on the hillside. There is always trouble there. I didn't change the actual racing line. I just re-recorded the left and right sidelines to get them through the final turn better and also to keep them out of pitlane. The original right sideline had them racing through pitlane for some reason. These should work with any of the tracks based off the original Longford_67 track. Make sure to backup the existing ai folder before extracting these. Thanks...
