Yes for rF2 track modding . Would be nice if you kept a list of where you got each object from, but I don't expect you to do that.
If you're talking about the current Adelaide street circuit used by v8 supercars, there's already a very good version by Digga.
That version is my version modified for RFactor2 I created it over 10 years ago for Sport Car GT then converted it to F1 Challenge. Have a look at it on youtube; https://www.youtube.com/watch?v=wLZOKKdCKEQ Im making a new version
