Hi I seem to have an issue that i cant seem to find a solution for.
My characters are looking like plastic. With shiny skin and everything.
I have tried changing the lighting and tried messing about with the skin texture settings but to no avail.
Can anyone give me an idea where i have gone wrong. It must be something i have done but cant seem to back track to when it started.
Please take a look at what i mean. Any help would be really appreciated

Assuming you're using Digital Human Skin for the shader it all comes down to your roughness maps.  How are you getting the skin in the first place?

but seriously,  a quick fix for this ...is to take the roughness and metallic textures and make them darker or lighter ...you'll see the change

there are other little tweaks scattered through the panel for fine tuning the "shiny" -  but simply adjusting the texture brightness / darkness at the base is a shortcut that prevents you from looking like this render after spending hours fine-tuning detail only an insect with 500 eyes will see on your smartphone.

You issue is usually caused by the 3 basics here:
1. Human Skin sweat settings
2. Light type...point and spots with no diffusion will cause harsh speculars (reflections)
3. HDR Effect & Tone Map settings.
