About this mod

Myrkvior uses 3D 'full' rather than 3D hybrid LOD models. This returns a few FPS to the user with improved hybrid models built using the latest DynDOLOD 3 tools. Hosted here until kojak747 is able to incorporate.

Compatibility
This add-on is incompatible with Fixed Mesh Lighting mod (if that mod ever updates Myrkvior meshes), because that mod alters Lighting Effect 1 in the meshes, thus changing the CRC32 values. I will not be revising LOD models for any trees touched by that mod, since I am not convinced this lighting tweak is useful for at least some tree mods. My testing has revealed that these lighting tweaks trade off one small problem (slightly glowing trees at night) for a larger problem, depending on the trees (very dark branches in daylight on non-normal faces, but still some glow on normal faces).


NOTE: This mod expects object LODGen via DynDOLOD 3 Alpha 39+ because DynDOLOD-TexGen 2 cannot create trunk/tree billboards ... and I didn't
include them with the mod, since people should only be using DynDOLOD 3 at this point anyway. It is much better for both mod authors and users.

Uploaded with permission from kojak747 to supplement his excellent custom trees.


This mod adheres to DynDOLOD best practice by ...
  • NOT providing tree billboards, which are now created by TexGen 3 consistently and at higher quality than is typical of hand-made billboards.
  • NOT providing pre-generated LOD(!), which will almost never correspond to the end user's mod list and only serves to add 'bloat' to the mod.
  • Providing the flat trunk models that are used by TexGen 3 to create trunk billboards, allowing the end user to substitute custom bark textures that will translate into LOD.


Description

This mod provides enhanced hybrid 3D tree LOD models for the excellent Myrkvior - The Flora Of Skyrim - Trees SSE by kojak747. His mod includes 3D static LOD created from crowns and 'full' trunks. I recreated all LOD models from scratch to use 'flat' trunks that significantly reduce the poly count of trunks in applicable LOD models for better performance and no perceptible quality loss. I also include NIF nodes that provide a bit more of the full-model detail to some trees and have created LOD for junipers and tundra shrubs. Due to their limited size, some of these new LOD models will not be generated by default, but they can now be enabled by using text-file 'rules' overrides or by changing global TexGen INI settings (see DynDOLOD documentation for details). Even with the new detail and models added and activated, those using Myrkvior should profit a bit with the return of a few FPS and improved lighting on LOD trees offered by the latest DynDOLOD NIF template.

Highlights & Recommendations
  • Recreated all 3D LOD models from base models - Roughly 20% were left 'full' and the rest changed to lower-poly hybrids with flat trunks
  • Lower-poly trunks increase performance without LOD quality loss
  • Hybrids created using latest template4.nif from DynDOLOD 3 for better reaction to lighting
  • Junipers and tundra shrubs also have 3D LOD models (small models may need TXT config to override DynDOLOD 'rules' limiting LODGen)
  • Corrected a handful of base meshes with incomplete texture paths
  • Created two normal maps missing from Myrkvior
  • Requires DynDOLOD 3
  • Recommended DynDOLOD 'tree' mesh rule: LOD4/Level0, LOD8/Billboard4, LOD16/Billboard (Level0 looks best for all but will tank performance)

INSTALL - be sure this mod's assets override Myrkvior's. If Morekvior-Myrkvior Visual Enhancement-DynDOLOD is also installed, the override order is:
  1. Myrkvior - The Flora Of Skyrim - Trees SSE
  2. This mod
  3. Morekvior-Myrkvior Visual Enhancement
  4. Morekvior-Myrkvior Visual Enhancement-DynDOLOD

Recommended DynDOLOD 'tree' mesh rules:
  • Ultra: LOD4/Level0, LOD8/Level1, LOD16/Level2
  • Performance: LOD4/Billboard4, LOD8/Billboard4, LOD16/Billboard´╗┐(1) (looks VERY good and may be optimal for many)
  • Optimal: LOD4/Level0, LOD8/Billboard4, LOD16/Billboard(1)
CONSIDER - Use TexGen/DynDOLOD 3 to generate LOD for Mrykvior, and save as mods. Then generate exactly the same way with this mod activated. Compare performance using SPM or another performance logger. Share your results (would be interesting to see variations in performance impacts)


For more information about using DynDOLOD 3.xx and all other LODGen, check out the LOD instructions on the latest Step guide.

None of this would have been possible without sheson (DynDOLOD fork) and the xEdit developers (base application)
