If you want to model and shade clay-like objects in Blender, then this is the right tutorial for you! Alexandre Albisser shares his techniques.
In this video we will create a handy toolbox for claymorphism compositions.
We will build the nodes setup for a fluffy clouds with animated flow, a setup to inflate any 2D design into a 3D base element made of clay, and a setup to create really cool clay noodles out of bezier curves with rounded end caps and perfect topology!
As for shading, this video contains tips to apply random colors to objects, tips to use any color you choose for different objects with a single material, and even tips to use different gradients colors on different objects with a single master material.
