Scuffed edit to merge the flat chest section of LittleLuxio's Bibo Flat normal textures with the Detailed version of the Bibo+ normal map to re-add things like hip creasing and pore definition, in standard and buff variants. This essentially makes the chest look slightly flatter without editing the model.
Requires a Bibo+ based body to function, but should be compatible with any of them. Unfortunately, due to this being a naive texture edit, this means that pore textures are lost on the breasts, but it was good enough for me. Vanilla scales only. Hroth not currently supported.
The following mods are used in the preview image: Bibo+. Thank you!
