ARK - the Unreal Engine - uses UV Mapping to apply textures. The default skin texture uses a mapping based on a symetric body model - in other words they modeled half the pawn and then mirrored the mesh.
For whatever reason, when they decided to implement body painting they just created a second UV Map, this time for the full body.
As this mod uses a new mesh i had to recreate this second UV Mapping and eventhough i used the same seams for unwrapping the models, the UV created is not fully the same as the vanilla models have.
For the time being I'm publishing the UVs used by this mod, for those that want to create body paintings for C'est Naturelle.

The UVs are 2048*2048, should be good enough for most uses as the original skins are also max 2048s ... If someone wants to contribute with better skins, paintings, etc ... Feel free to look at the github site https://github.com/baby-doe/cest-naturelle

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=518296250 is a PNT helper app that seems to work well with the PNTs generated by C'est Naturel ... You may want to look into it

i think, last update (258) broke the painting sometime it work sometime it dont work xD i tested 5 time with and without mod (so 10 reboot of game in total) 3/5 time work without mod, 0/5 time work with mod, so i guess new UI messed thing up , so would recommand wait bit before do ur painting thing time ark fix it , or idk xD (unless only me having the issue xD wich is rly wierd one XD) http://prntscr.com/fdsz11

Just posted a picture of Jane with tatoo ... Done today using the tools described above ... It works ...

My way
1. Export a dummy pnt
2. Open Gimp create a new blank 2048 *2048 canvas
3. New layer with the UV Map posted above - female or male, depending on pawn
4. New layer apply the Tatoo using transparencies, zooming, etc
5. Remove all layers but the tatoo and resize to 512*512
6. Export as PNG
7. Open ARKpnt Ed and import the dummy pnt
8. Load my new tatoo and convert colors to ARK palette
9. Save as pnt
10. Rename to mytatoo_PlayerPawnTest_Female_AuNaturale_C.pnt
11. Load the tatoo in Ark, will be named mytatoo, or whatever else you named it

Keep in mind that you need the PlayerPawnTest_Female_AuNaturale_C or PlayerPawnTest_Male_AuNaturale_C suffix or it will not load ...

Finally got around to doing some body paint!!!
