Is this a beta or a release because I seen some mistakes that a designer should not make.
When I designed Hazeltine National I probably playtested it 60 times or more, you have to play your course so you know what your missing. You won't find everything because sometimes you just miss it but you must playtest a lot, you should not rely on playtesters until you really think it is ready for release and then sometimes they will find something and then you have the choice to fix it or not.
Overall I think you did a nice job but it could have been better with these issues fixed. If you don't fix the glaring ones and just let it be you won't get many people playing your course and as a course designer this is why you design golf courses. I did not go thru the course with a fine tooth comb because it's pretty early in the morning and I got some things to do but fix those issues and upload a newer version please.
Issues I seen,
1. It seemed like you were using Lidar, you should have painted the outside where it still shows the overlay because you can still see it and it doesn't look good.
2. Ensure all tee boxes are surrounded by rough because that just looks LAZY and BAD, I don't see tee boxes raised by 5 inches in real life.
3. Ensure all bunkers are surrounded by rough and from what I seen I think you did that but I did noticed hole 12 I believe had two bunkers on the left that you did not surround so they float above the ground.
4. Green on hole 3 as Dave seen above, need to move a point or three and rebuild the splines on that green and that should take care of the problem.
