I have a problem when i go into TStools check route i have 552 missing files. Welshmarches Scenery/clutter Scenery/Global Scenery/Treegen.bin Files. I have unticked the route deleted from my content folder reinstalled same problem.
I have unpacked the AP File through 7 zip.As to the route looking on you tube my route looks very sparse and the trees around Shrewsbury looking very bleak in on a summer scenario.
There's nothing wrong with the route. You shouldn't unpack an .ap. TSTools shows errors because it can't look inside the .ap pack (which it says in red letters). Why not post a screenshot? Have you made sure Scenery Density is set to max? And maybe the video you have seen uses AP vegetation enhancement which replaces the bland giant leaf balloon shaped DTG trees...
None of the trees or any other asset that you are missing are stored in the Content Folder. That is just a map. The folder to remove is \Assets\BMG\WelshMarchesLine - or just rename to to WelshMarchesLineX Untick and re-tick in the Steam Client
