They also want us to reduce texture sizes on lower LOD’s. To be honest I
disagree with it, please check it here:
https://devsupport.flightsimulator.com/t/3239 On the last LOD they want us
to use vertex colors instead of any texture. Creating the LOD’s is not that
hard. But if you have hundreds of objects like me, it takes a while 
Especially editing the xml’s and finetuning the LOD minsizes.
