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.
