The programmers aren't generally artists. However, they are trying to get the most out of the program. In this case, it also means working towards higher detail. Granted, it hasn't been as easy as first thought. But we are still working on it.
By doing what has been done, it has opened up discussions between the programmers and the creators. If the change hadn't been made, well we wouldn't be trying to work out how to make higher detail trees. Instead we would become stagnant and continue using billboards. Very few, if any, new commercially released games are using billboards these days. They just don't have the detail in them, in terms of 3D. The aim was to get higher detail/res trees.
Now, I did word my comment above poorly. What I meant to say was "In many cases, such as trees, it is good to have the community work with Auran to figure things out. As they can then all throw ideas between themselves. And work towards having it work in the best possible way". Which is exactly what is happening.
And through this, a bug has been found and reported. This bug would have gone basically un-noticed as the other other assets that show it, show it at a point at which it isn't noticed.
As before, the trees haven't been as easy as first thought. But they are moving forward, again.
Now, my second 'silly' comment. I say that you guys aren't going to like it, because it isn't as easy as it used to be. We see it time and again on here. Most users don't like seeing things change. In this case, you are going to have to change your technique for building layouts. Simply by choosing how far from the tracks you want high detail trees before changing to mid/low detail trees. This is what people won't like. Changing their technique. This is just a guess of the reaction based on past reactions to change on the forums.
Basically, you will need to manually LOD your layout. Myself, I like the idea. Namely because I have control over where the low detail 'point' will be.
Mind you, the technique itself has been in use for a long while. Many users have high detail near the tracks, and then lower the detail further away. Trees further apart, less buildings, less splines, no fine detail, etc. Well, it's the same. Just you need to use 2 different trees.
Have fun
