As soon as I saw that someone had been making an RCR of Wolf Creek, I immediately came here. For the multilevel water, I want to say that TGC 2 will have that available, but if you can make Wolf Creek in the original game, I (and hopefully many others) will be very impressed. Hope you do well with this, I would love to play this course in its entirety on TGC.
Edit: Played both, noticed a few things. I'm not sure of this, but I think a few of the elevations from the tee are different (unless you're just using different tee boxes). I'll check with the Wolf Creek of Rory McIlroy. Other than the sloping of the 6th green and the background having no mountains (I assume you're doing those last), it's pretty good. I especially liked 1, 5, 7 and 8, those were nearly spot on.
(I also liked 3 for realism, but I hate 3 from a playing standpoint with a burning passion.)
Edit 2: All 18 holes from the furthest tee boxes, according to Rory McIlroy game (Most are estimates, give or take about 5 feet)
1: 575 yds -50 ft
2: 445 yds -100 ft
3: 240 yds +93 ft
4: 400 yds +30 ft
5: 520 yds -35 ft
6: 415 yds -90 ft
7: 310 yds -50 ft
8: 250 yds -86 ft
9: 380 yds -10 ft
10: 455 yds +45 ft
11: 215 yds -82 ft
12: 570 yds -95 ft
13: 350 yds (310 to green) -5 ft
14: 470 yds -130 ft
15: 130 yds -45 ft
16: 420 yds -70 ft
17: 555 yds -170 ft
18: 310 yds +15 ft
I seriously can't wait to play this, good luck with it. Hope I helped.
