Couple things. Yeah I remember this being attempted, Sam I don't think it was you. It was called Ex-Trespasser or something. And yeah I don't think it got very far.
I spent some time recreating IJ, also combining it with IT and trying to make the Plains... I got kinda far but still have much work to do on it. It is however part of my project idea to recreate the entire game, the aim being not to improve everything but to restore the original vision of Trespasser to the actual game. This is mainly things like lost levels (PV, ascent levels) and removed puzzels (capacitors, Summit comm tower circuits), as well as foliage density that was reduced for framerate.
I still plan on doing this, right now I'm mainly involved with PA - machf is working on the level between Lab and As1, which I think he's linking to As2.
BTW, about that. I think I've figured it out, and I plan to set up the levels based
somewhat on this. Ascent 1 uses the terrain file "as.wtd" and Ascent 2 uses "as4.wtd". I believe as4.wtd initially only covered the area from where that road comes in from the other side to the elevator at the top, used for a level called Ascent 4. Now, if we assume there was a level right after Lab dealing only with the Paddocks, it would lead either into Ascent 1 or Ascent 2. Ascent 1 would be basically what it is now and lead up past the Mayan pyramid. Ascent 2 would go up around the mountain the other way - perhaps there was a seperate forest path that preceeded this, after the paddocks. Ascent 3 would be what most of Ascent 2 currently is, starting with the race down the hill and around the corner from the raptors and beginning up the mountain at the Mayan statues. It would end instead at the point where the road that curves around from the other side of the mountain joins with the path. Ascent 4, as I mentioned above, would be everything from that point until the elevator, though that does seem like a fairly small level if memory serves.
Anyway, this is basically how I plan to set up the levels when we rerelease them. At some point I must speak with machf about leading his paddocks level smoothly from the modded Lab level into either As1 or As2 (modded) - I want to make it begin with the very first paddock (rather than after it, where Lab currently ends) to make it not only contiguous with the other paddocks but so it makes more sense how you move from one level to the next. Actually though - from the sounds of it, he'll be including what I've identified as the old Ascent 2 in his paddocks level.. machf, what if we eh.. changed that a bit? Lol it's just an off idea but - we could make some more forest area off to the side, leading up to it, and possibly stick the Hidden Village in there to give it more interest in seeing (which btw may have been what made old Ascent 2 worth seeing - you either enter the Mayan ruins or the old colonial Hidden Village, both of which were hinted at in PV. The only sad part about that is that I had identified a nice area in Ascent 1 where it could go.. heh but you may not want to change the level that much so I might just stick it in Ascent 1, anyway.
