Perhaps just have to keep it simple without any fancy strategies for future, and get my mods where they can be without overkill on myself, because it takes a little bit time to model things.
I also don't feel very well working on same thing over and over again. I think same goes to people who are using mods. They gets tired to update same mods over and over again. I know that often people just stops updating, for example still using first releases, because those versions are already fine for them, or just gets their "try" of the car/track. I am not exception, there are lots of great content, but I just simply don't have that time. Also just driving is not interesting anymore, racing against AI is ok, but the real thing is racing other people. There really isn't much motivation just to drive something after 500-1000km driven, or often much less than that. But when there is true competition things change. But mods aren't used online, they weren't even used much when community was going strong in official forums of AC.
Moreover, people starts feeling bored, their expectations and demand grows. Last update was a bang IMO, but there were lots of negative responses. Even though car was better than previous version. Even same people who were happy about it before, weren't happy then. I think it got too unique, which I thought was awesome, but people probably found it requiring skills which other cars in AC didn't need.... But next update will have physics which will make it more like normal fresh car.
I am no exception, I really dislike iRacing Lotus 49, but I think I have a good base for such opinion, rather than just "hard to drive".
To sum it all up I can puts lots of effort again, but it could not be worth it, might not come back. I have some other mods. Already released or just having some hours put in blender: Nemunas Circuit, Goodwood Circuit, W125, 312 P Berlinetta, Jaguar D-type, Jaguar E-type. Would be happy to really finish them for something fresh, with community still being hungry, that would really motivate. Meanwhile existing mods might be improved, and probably will be, there could be new releases. But true finished project means something else. Keep in mind that XJ13 is my absolute first thing I have built in 3D, there are many little things which needs to be improved, just look at GT Sport XJ13 version... I am not sure if it is worth to give my heart out again for whole thing revision, some elements - maybe.
But it will really loose skins you know.... :/
Maybe something could be sorted out about LODS.
