One beer or whatever ^^... So... First, it was my bad, i've checked all my 200 mods in the tes5 box before applying Dyndolod Script..... - I only checked now the "vegetation mod" and LOS and magically, the 2D trees has disapeared in Whiterun (no need to check town or villages mods I think)... - I've moved when even all the files in texture/terrain... as you recommended me. - I don't know what i've forgotten but my trees aspine are still becoming trees pine at mid distance (see links) : https://i.imgur.com/26tyLfC.jpg?1 https://i.imgur.com/viT5OOj.jpg?1?1639 - Below, my actual list mods with the same load order. Only checked "Skyrim.esm", "Update.esm", "vegetation mods" and LOS (in green). May be I should check in others ? Thx for the help ! :)
