Hi everybody! Today I'm going to show you how to make a red eroded coral material in blender / cycles: ¡Hola a todos! Hoy voy a mostraros como hacer un material de tipo coral rojo erosionado con blender y cycles: This is the overview of the material: Esta es la visión general del material: This is the zoom on the left hand side in the material: Este es el zoom de la parte izquierda del material: I have mixed three Voronoi Textures to get the bumping of the material (see turquoise frame). I have used a Value node and two Math node with the Multiply option to centralize the scaling my textures. If the value of the Value node is changed, all the textures changes in the same proportion. By plugging these textures in Bump nodes and chaining them I get a kind of eroded surface. Regarding the purple frame, I have used two of the Voronoi textures to find the holes on the surface and set a different color for them. They are the white spots of the coral. He...

Hi every body. Today I'm going to show you a scratched metal material: (1) Preview of the node setup explained in this article  (2) Preview of the node setup with parameters modified for the last render below This is the basic node setup of the material: As you can see, the material is a simple Glossy node wich is added a scratched bumping. You can change the Glossy node by another metal or a material of you own. The main element of the Scratched Pattern node group is a tweaked Voronoi texture, which produces a streaky pattern: This is the Map Range node group included: This tweaked Voronoi texture produces some spots painted on your texture. The number of spots depends on the Threshold parameter (1.0 for all spots, Mapping Vector node scaling the texture in this way: The Scratched Pattern node group contains eight groups of  Mapping-Tweaked Voronoi nodes. This is the comparison of one Tweaked Voronoi or eight of them with differ...
