Hello everyone,

I have a problem with the SSS shader. I have built a SSS Shader based on the Specular Material. What I want to do now is to integrate the Dirt Node into this shader. For example, if I link a Dirt Node in a Universal Shader into the Albedo I get the effect I need. However, there is no albedo input in my SSS shader. In my shader I use scattering as medium. So basically I want to multiply the dirt node into the SSS shader. I have tried the following ways: Via a composite material, material layers and via the realtime compositor I mixed a diffuse material with a dirt node with my SSS shader. However, I am not getting exactly the result I want. Then as a last attempt I built a SSS shader with the universal material where an albedo channel exists and then added the dirt node and it works and looks good. Problem is, the SSS Shader based on the Univeral Material does not look as good as with the Specular Material. can someone help me with this? I hope I could express myself well if not I will provide some screenshots.

Thanks for the support, cheerz

Be sure to use Fake Shadows in your Material.
Also, the Universal Material offers 2 Transmission Type options, Specular and Diffuse. Did you try those?
By the way, Random Walk is what I use every time I need SSS materials in my projects.

Seconding Lino's RandomWalk suggestion.

By the way, worth keeping an eye on this page, soon to be completed. Universal, Specular and Standard Surface have been used, RandomWalk medium included.

Hi all, thx for the useful replies and sry for late answer. Yes, I finally managed to get it work! Thank you very much!
