Skin Shader for Octane Render
If nothing appears, you probably haven't read the warnings in the readme.txt file.
The screen is black because there's no light.
A texture used for global illumination is missing.
The readme.txt file clearly states that this texture must be downloaded; I can't attach it due to licensing issues.
Alternatively, you can replace it with another texture or place some lights.
This is a temporary issue due to a bug in the current version of Octane for Blender (28.4). The problem has been reported to OTOY and is being resolved. It will be fixed in the next Octane build.
In releases of Octane older than 23.8 (based on Blender 2.92) there are some bugs about color inputs in groups so it was necessary to add some redundant inputs then removed as soon as this bug was fixed.
The nodes affected by this change are Diffuse Color and Specular Color.
Yes! This shader is compatible with all Octane Render releases from Blender 2.8.3 until Blender 2.9.3.
