aggggghhhhh, now i have the same problem. Must've successfully run TexGen and DyndoLOD about 10 times last week. I've managed to get TexGEn running and have my output file, but needing to run DyndoLOD which is a whole nother story. I'm now getting the same error messages as posters above. I've attached my log for reference. Any help anyone can offer is greatly appreciated. Many thanks in advance, DynDOLOD_SSE_log.7z
