I emailed Günter Kujat a few weeks ago, to ask if he was ok with me making an update of his classic course Munchen Nord - Eichenreid (last release came in 2002). He gave me the go-ahead, and also said it was nice to see that the Links community is still active

Planned Edits
Some might be asking whether this course even needs an update. I know the course is a great classic and very nostalgic to a lot of Linksters, and I agree that it is an extremely great course for having been made in 2002. There are, however, sadly a few things about it that makes me and some other Linksters unable to enjoy this otherwise magnificent course in our seasons. Mainly, a few greens leave very few options for pins that are fair and realistic on the modern realistic pro tour green speeds. One green (8th) doesnt even feature a single acceptable pin for people with a taste for realistic pins.
There were a few other things I had in mind to perhaps update as well:
-A few areas are currently left without seamblending (mainly the greens and fringes), and while the fringes might be a little tricky because of the structure of the mesh, I have an idea that I think will give adequate results, without messing with the mesh too much.
-I think the current textures are pretty nice, but I think some new 1024x1024 ones for the main surfaces could be an improvement. It can be achieved without the colours of the course being changed.
In my original message to Günter Kujat, I invited him to let me know if he had any thoughts or preferences about these type of details of the update, including a few specific ones, which he didnt say anything about, so I take it he leaves that for me to decide. Naturally, my goal - as always when I make updates - is to change as little as possible while still making an update which I (and hopefully others) will be satisfied with. After having a closer look at the course, I found a few other things that I would like to tweak:
-The greens currently have very few verts inside of them (average 8 per green), which would both have an irregular-appearance impact on the upcoming green seamblend, and also tends to make greenslopes less naturally flowing. Therefore Im going to need to make more verts on the greens, which will inevitably change the greenslopes somewhat, but my goal is to do it in a way that will change them as little as possible, while still producing realistic greens and making the seamblends look even. I can say that I want to avoid making the greens easier overall.
-I want to change the default wind direction, to what is more common according to wind data sites for the Munchen area (specifically in June, when the tour event tends to be held).
-I think the planting on the course is its greatest strength, very admirable, not least because of having been made in 2002. So initially, my plan was to not touch the planting at all. I quickly realized that there are tons of objects set as 'tournament objects' on this course, and those tend to revert to non-tournament objects when saving a course with a different APCD, so I will have to carefully go around and re-plant all those in order to not change them, but that should be doable with some patience. I did spot some bushes that seem to have somewhat glitchy shadows when seen from certain angles (at least on my end), for example the ones by the ditch/creek which you hit across on 18th. I think I will be able to re-plant those the same way they were, except for removed shadows (those bushes dont look like they need any shadows).
Now we get to the main thing I am looking for opinions on.
About Layout Changes in Real-Life Since 2002
Initially, my plan was to leave the layout exactly like it was. I knew that the course was likely to have changed at least a little bit here and there since 2002, but I didnt feel like there was a need to change that, the course plays really fun the way it used to in 2002 if you ask me. Anyhow, I still went ahead and compared some historical satellite images on Google Earth Pro, mostly just out of curiosity. I found that the layout has changed very little since 2002. A few bunkers added, some removed, some bunker shapes changed a little. Most of those changes are in areas where they wouldnt really effect gameplay in Links, so I dont think such changes really matter to anyone. As usual with courses in real life, fairways tend to be mowed in different widths and shapes from year to year, and some have indeed changed a bit, but I dont see the need to mess with that since the 2002 version of the course was so well-liked in the first place. You can make the fairway areas accurate for a certain year, but then they might be all wrong next year again anyway... Trees, well they grow and sometimes fall or get removed. I havent looked into them that closely, but I personally dont see the point in messing with them.
On two or three holes they seem to have built a further tee area since 2002, I looked at those holes and thought "well, I dont think those further tee areas would make the course play more fun with Links standard club distances..." They seem designed for modern real-life long hitters, and might only serve to make the tee shots less strategical for Linksters. On hole 6 however (a par 5 that can currently be reached even with a Driver + 5 Iron), I think the newer, longer tee could be pretty nice for Links, because Im pretty sure the hole would still be reachable in two. When comparing a modern BMW International Open scorecard to the 2002 Links Scorecard, there are some other differences here and there, where they didnt build a new tee area, but simply put the tees on a different spot compared to the 2002 version. I dont particularly feel a desire to change those personally, because I've looked at them and I feel like most of them would not make the layout play more fun in Links. Obviously that can be subjective but that is my spontaneous feeling. So the tees Im a little torn about what to do with. On the one hand, it might be a little weird to change them only in SOME places, while leaving others as they were... But honestly that is what I think would make the course most fun. Would love to hear what others think.
Finally, here is the big one: I did see a couple changes they've made to the design (around the years 2005-2016 I think it was), where they made a few ponds come into play more by making them larger and closer to the greens on holes 11, 16 and 18 (and perhaps to a tiny extent hole 12 - the short par 3). See the picture below.
I admit it, Im a great sucker for holes with water hazards close to the greens. Especially on par 5 holes. It makes for such excellent risk-reward strategic choices. I am extremely tempted to make those particular changes to the course, I think it would make at least holes 11, 12 and 18 a lot spicier and fun, because they are rather easy holes normally. Hole 16 is a driveable par 4, and Im less certain about that one. It is already pretty difficult and somewhat risky to try reach with Links' club distances from the Back tees, and the water change (together with the default wind direction change) might make it too difficult and risky to try reach, so as to not make that option at all worth considering anymore unless playing from the shorter tees.
So... to summarize about the layout, here is where Im at currently: If I was making this update only for myself, I would just add the tee on hole 6 and change the water on holes 11, 12 and 18, and not change anything else. But Im not trying to make this course only for myself, and I dont know whether anyone else thinks it is too weird to only change certain things, or what preferences people might have. Perhaps some of you even hate water...

One idea might be to split the update into two versions - one Classic, unchanged layout. And then one Renovated. Honestly, Im not too keen on making different versions unless it is really necessary. I also dont feel particularly keen on going through and renovating every single little layout change. But if enough people would enjoy that, then maybe...
If anyone considers it heresy to even consider updating the course in the first place... the original versions will still always remain available... no one's going to force anyone to play the update...
