Create a low poly wallpaper in C4D

First off, fire up Cinema 4D and add a platonic shape from the shape menu to your scene. Select the shape in the objects menu and select the object tab in the Attribute panel below. Change the type to Bucky.

Next, select a Displacer object. This lives in the same menu as the Bend object. Move the Displacer inside your Platonic shape in the Objects panel to make it a child of the shape.
Once there, select the Shading tab from the Attributes panel below. Next to the shader, click the little white arrow button to be able to select noise. Once selected, click the object tab and alter the height. This will start to create the kind of shapes we’re looking for.

As well as playing around with the height and noise attributes, you can also tweak the attributes of the Platonic shape, like its type and segments. This will give you a more detailed shape. It’s worth playing around until you get one you like.
Next, we’ll need to add another shape to our scene. We’ll use this later to project colour into our Platonic shape. So select a cube and in its Attributes/Object panel change its X/Y/Z size to 2000cm. This should surround your Platonic shape and still allow you to see it.
