Keynotes about the custom shaders used:

The custom skin and eye shaders, while inspired by those used in CC Tools, have been extensively reimagined and developed to become unique works on their own. They feature brand-new features as:

• Subdermal color zones for a more pseudo-realistic look. Two modes avaliable.
• Individual cutout masks to address clothes poking through in a straightforward manner.
• An overall optimization and simplification of variables.
• Skin pseudo-decals support.
• Customized Shaders' GUIs.
• Eye decals to give a unique touch to your characters' gaze!

Skin and Eye shaders for the BRP and URP were created with Amplify Shader. While not required, it's recommended for those wishing to edit them. The skin and eye shaders for HDRP was developed in Shader Graph. The hair (and brows and beard if any), as seen in the promo images, uses liltoon shader for the three render pipelines and is included in the pack up to version 1.7.2. under the MIT License. For the best possible results, especially for the skin, consider using a proper Post Processing Profile (an example is included for the three pipelines) and at least a 3-point lighting system (demo scenes are available for reference).

About the textures:

PBR: Diffuse, Metallic, Specular, AO, HDRP Mask Roughness, Normal (not always all for each mesh, adapted for each render pipeline).

Avergae size: 2K-4K.

Most textures used for clothes and skin have a size of 4K for demo purposes. You can easily downsize them to fit your project requirements.

Character is presented in an unique mesh. Clothes are separated. The character can get fully naked and and get attached new clothes via third party softwares.
