HiPoly Faces REDUX (Seamless Kit - CBBE - TWB - FG) v1.2.1  

This is the long-overdue revamp of the HiPoly Faces. Years in development and testing, months in limbo, and now finally released.
HiPoly Faces REDUX (HFR) is a complete, ground-up rebuild of the original mod. It gets rid of all the small (and large) issues that the original had and is better in every way. Plus, now it has many more useful newly added features.

As with the original mod, the polygon count has been kept to a reasonable level, so no performance issues, even on weaker systems.

Requires:

LooksMenu
Mod Configuration Menu
F4SE

Recommended texture mods (use one):
Cridowskin (with HFR seamless patches)
Serene Skin (works with seamless but has its own Skin Overrides so make sure to read its instructions)
Real HD Face Textures 2k / (BA2)
Natural 2K Face Textures

Note: I have not tested these mods thoroughly. They may cause color mismatches when using a seamless config, please keep that in mind.

Improvements vs the old HiPoly Faces mod:
-No silly preset edits, console commands, or records edits are needed to load this onto player characters and companions anymore. Everything can be done using MCM.
-Better smoothing algorithm used. This allows for smoother faces while preserving facial volume and detail.
-The better smoothing also gets rid of facial tattoos being warped.
-Customized face normals get rid of any unwanted shadowing and roughness.
-Added segmentation data to the meshes.
-Now includes an optional head and neck seam removal kit. By default, this is a standalone feature for the player character only.
