Polygon Pen shows how you can model and bake tileable patterns for textures in Cinema 4D.
There are many ways you can use to make tiling materials in 3D, often from 2D sources. This new tutorial from Polygon Pen shows how to derive tiling patterns for textures by making and baking a 3D model.
The tutorial shows how to make a rubber grip material for a game controller by modeling the pattern first and then baking it onto a simple plane in C4D.
