Hello Sheson, To clarify, I love what you've made with DynDOLOD, my issue is this particular (crappy) tree taking up more resources that it was worth. I'll try to respond as thoroughly as I can, I don't have much testing time what with a new baby and all. You obviously know more about this than anyone, so I apologize if I can't be more clear. Also I've solved the problem to my satisfaction, setting Static LOD8 for this tree effectively dealt with the issue. I'm not sure though, if there might be a bug somewhere, that might help others if squashed. -I believe that EVT and SMIM come with full models of this tree, while EVT and DynDOLOD Resources come with the hybrid models. When I say both, I mean that I have run trees through EVT SSE, EVT Oldrim, SMIM+DynDOLOD Resources. all separately with the same result. I think I ticked "replace tree" to see if I could get DynDOLOD to look for (or tell me that it's looking for) the hybrid model. In either case, I tried it with both replaced, and unchanged. -I don't remember where all the versions of this tree came from, but I have about 4 identical hybrid trees of this with different names. The issue for me is that at Static LOD4 this (and only this) tree does not seem to look for the hybrid model at all. Or it does but it decides that the full model is the hybrid model. I only run EVT, or Vanilla+SMIM+Dyndolod Resources. -I sort of mean this as to say "I have tried this many times", I'm not sure what all the differences would be, but I've tried many variations on those differences if they actually exist. -When I was first doing this the naive - easy - way I noticed this tree always used a full model. In my versions for DynDOLOD SSE, If I clicked "Load Preset" and chose the one called "Default", it added in the tundradriftwood entry to the main list. I worked off of that, and my limited knowledge. -When I use Static LOD8 where Static LOD4 should go, It looks for (and finds) tundradriftwood01passthru_lod.nif, no CRC number attached as per my log. I don't think I have any lods that have "*_lod_1.nif". - The log shows that "3D Lod found" but points it to "tundradriftwood01.nif" as the 3D LOD, the full model, instead of passthru (when set to Static LOD4, in LOD4 settings) -I'll need to check this. Again limited time, baby, no sleep, dying. Thank you again for this magnificent tool.
