Using the SFO v2.5b removed the new trees, so the LOD are no longer a problem. I think I am fine without the special tree types. I have one more question, I installed the "Tall Pines" optional file, but it is being overwritten by "Enhanced Vanilla Trees - Bilboard generator". I tried putting the "Tall Pines" after EVT, which seemed to work (the distant trees also looked much better), but there were some problems with LOD sizes, after running DynDOLOD. Looking at the "Enhanced Vanilla Trees" mod page, the author specifies, that no other tree LOD mods should be used. One last question: When using DynDOLOD, my settings look like this -> https://imgur.com/a/cUD6D . Is this correct, or should I skip the "Generate tree LOD"?
