When you’re trying to create a wet environment, properly setting up your surfaces to look damp is obviously vital. Perfecting that effect in your project couldn’t be simpler with this easy-to-follow setup.

To begin, select the model you want to make wet and assign a material to it. In the Shader Editor check Use Nodes, and we can begin the creation of the material. By default we’ll find the Principled BSDF shader in the material created, which will form the base for the wetness effect, and then bring in a Mix shader and connect it to the Principled BSDF.

Now we can add in a Layer Weight node and connect it to the Fac input of the Mix shader to help control the wet surface’s reflection intensity. Meanwhile, the Layer Weight node’s Facing setting controls the distribution based on the viewing angle; that means you can adjust this parameter to make the wet effect more pronounced when seen at certain perspectives, just like in real life with puddles and similar surfaces.

In order to see the reflec tion we need to add a Glossy BSDF shader and connect it to the second shader input of the Mix shader. The Glossy shader will simulate the reflective surface, and by adjusting the Roughness parameter we’ll be able to set the intensity of the reflection on the wet parts of the surface. In general, lower values make the surface appear wetter.

Now the surface
