At first thanks you try to help me,, :happy: then I need to apologize because My question is only about Skyrim SE CK, then I ask in wrong forum :sad: I forget,, CK64 means,, simply CK,, not means CK for SE... but my problem is only about CK for SE.. I serched forum for SE CK but, I could not before.. but I found now :pinch: Then actualy I already made original custom race (it is duplicated from default human race (nord), then I believe I use same work flow. as same as your suggestion. usually I use ECE or Racemenu then export facegen data,, and use nif merge tool (or Nifscope) to adjust node name, then have made many custom followers. but CK for SE show unique behavor about facegen datas. ( it is really annoying for me,,) skyrim CK never overwrite facegen mesh and texture, untill I click ctrl + F4. on the ohter hands CK for SE everytime re-generate facegen data meshes. when I save esp which use facegen data. It happen about all NPC mods which I currently used too .(they are offered as SE version,, so I believe my way is not worng.) (We have no easy way, about SE , to export facegen nif with ECE or Racemenu,, then when I make NPC , I usually use oldrim and CK, then make mod for oldrim (skyrim LE) then,convert it for supecial editon version,,,, but final adjustment need to work with CK (SE). Anyway,, I may up-load question, in Skyrim special editon forum.. I google to serch same question, but most of them are not replied,, then I feel if there is way to customize CK (SE) with ini etc,,, and forgive me,, if you said about CK (SE), I may need to check again.
