Does the GPL Alpha of this track still exist somewhere?
From the old Tasman site or maybe RSC I can remember there being some clipping issues, that were trying to be overcome
Were you on the original team then or do you just have a good memory? I have the alpha that Monza Gorilla passed on to me with the consent of the original team who had all moved on from GPL by that point. To me, the layout they had seems pretty good and gives the right sorts of times in the right sorts of cars, although it might be a touch too quick, but then so is GPL at most tracks by around 4% IIRC.
You are right about the clipping. The interesting thing about inheriting the project is that I got lots of experimental files from them of ways they tried to stop the viaduct from clipping by making it in various different ways. As a student of track making that is very interesting to see, although given all the things that they tried already, it is maybe not so obvious what to try next to fix it. In some ways it is often easiest to just restart a project rather than trying to pick it up where someone else left off, although given all of the work already put into this one that would be a shame.
Having got Surfers Paradise finished, I had hoped it would kick start a programme to get the remaining "missing" Tasman tracks completed. I have alphas for all four remaining missing tracks in fact, including Warwick Farm. The problem is that after finishing Surfers there was a certain amount of burnout and since then, despite best intentions I have had very little free time to get stuck into any of those four, (or indeed another two or three) ongoing track projects. It remains my intention that eventually all of these projects will be completed, if only that I have enough personal investment already in these projects that I don't want to go to waste. Just need to get some free time...
