Has anyone been able to succesfully mod an existing character face (i.e. Hitomi or Kokoro) and inject it into the game? I have some experience with sculpting tools and wanted to test it on doa. I used TMC Polygon Tool to extract the meshes i wanted to edit. Next, I opened the mesh in blender and made a few quick changes and exported the mesh using the plugin. The problem occurs when I attempt to use TMC Polygon Insert tool to reinject the mesh. For some reason when I choose the mesh file, which was originally associated with WGT_Face, it's only showing me MOt01_Head4 and MOt01_Head 5. Even if I select the box allowing me to insert into other meshes, WGT_Face still isn't an option.
It's possible my tools could be outdated because I haven't been actively modding (I'm using Polygon tool 0.5.1 and Polygon Insert Tool 0.2.1) and that could be the problem. Or it could be something else entirely that I'm missing. Is there a more convenient way to do this now that I'm not aware of? I see @bbb and @huchi001 are doing great work so they are on to something
Its possible, i have edited the tmcmesh for hitomis face for my gothic mod. I edited the eyebrows to have a more pissed off look, and edited the weights on the mouth so she smiled less. also added piercings to the face. I did some other changes too but reverted them since I didn't like the way they turned out.

some character faces have certain meshes not seen by polygon insert for some reason, it might have been fixed with the recent updates, but haven't checked. if the newest still don't work, you can try harry palmer's tmc->obj converter huchi said to use, but you can only move verts with that, and cant edit weights/delete and added mesh like with tmcmesh.
I think they are cool or not? Btw i have only put the wings in OPT_wings_Root_0 and that is the result.
I think it's all about bbb, because that is his tatto
you just need to swap the tattoo textures with the wing textures to get the original back
