The organic parts have been textured, rigged and groomed.
One interesting thing about shading the hair was that I got a smoother blending of the individual hairs with the surface beneath in Eevee when I used a decent amount of subsurface scattering.
The objects are placed closer together during the painting process as the armor is textured separately and thus empty space can be stripped away. I keep those objects in a duplicate collection so I can reference their transforms, should I need to redo uv unwraps, and can thus recreate the texturing transforms so the brush strokes can be reprojected.
