Beta 3 still overwrites 3 entries from Realistic Water Two with vanilla ones, namely "MHDT Max Height Data" as well as "NAM3 - LOD Water Type" in Worldspace\0000003c\ (Tamriel), "XCLR - Regions" in Worldspace\0000003c\00000D74 (Persistent Worldspace Cell) and "XCWT - Water" in Worldspace\0000003c\0000BCAF (RiftenCityNorthgateExterior).
Was that reported already? Anyhow this is fixed with
DynDOLOD Standalone 2.36 beta 4 that I just updated in first post.
Falskaar error this time (texgen):
The file is correct and LODGen runs fine with it here.
To just run LODGen.txt for a single worldspace again, change set Expert=1 in ..\
DynDOLOD\Edit Scripts\
DynDOLOD\DynDOLOD_SSE.ini, then start as normal, select worldspace from drop-down, click "Execute LODGen.exe" button.
See if it works then. You can then just merge the meshes folder from output.
Is the D:\Documents a special windows documents folder? Maybe try another, new folder and running everything as admin. Something 3rd party may be interfering.
Check if the installed Microsoft Visual C++ 2015 Redistributable x86/x64 is the latest version.
