Sorry, bit of a misunderstanding, I think.
I think it is
@Shokeus who made the older version. There was a street version (BT62r) and a race version (BT62) available at the time. The street version was fine, but the race version had an issue with its ground shadow.
Your new mod is obviously the better street version of the car now. But Shokeus' race version of the car was great, and I really enjoyed driving it. Unfortunately the ground shadow became too distracting for me during replays and I got rid in the end.
Hence my question as to whether it had been fixed. It was more directed at Shokeus. The version on Assettoland still has the shadow issue, but I was wondering if a fixed version had been linked elsewhere.
