SME stands for Skyrim Modding Essentials. It's a wabbajack list with all sorts of bugfixes, frameworks and tools that allow you to start modding Skyrim SE. It comes with DynDOLOD Resource SE, DynDOLOD DLL SE - Scripts and DLL, DynDOLOD DLL NG and Scripts 3.00 and xLODGen Resource - SSE Terrain Tamriel.
SME had a recent update and they updated Texgen. It works now.
