Realistic Sims 4 Skin Creation

I need a custom skin for The Sims 4 that looks convincingly real inside the game—subtle pores, natural undertones, dewy and smooth blending across all ages and genders. The final .package file should install without conflicts and work with the latest Sims 4 patch.

I have my own reference picture as well.
Please use your usual texturing tools (Photoshop, Substance Painter, Blender, or similar) and any in-game testing mods you rely on to make sure the skin renders correctly in CAS and in-game lighting. I would like:

• 100 % original textures (no edits of someone else’s CC)
• Separate default-replacement and non-default versions, if possible
• Clear thumbnails and swatches that match EA’s style

You can share low-res previews first for feedback; once approved, deliver the finished high-res texture files and the compiled .package. Looking forward to seeing your artistry bring a lifelike touch to my Sims.
