El Brujo de la Tribu

Hi everybody. Today I'm going to show you how to make a realistic plastic material like this: Firstly, I recommend you to see this video tutorial about how to setup a SSS node in Cycles made by @pauljs75. The overall setup of the yellow plastic is as follows: I have used two SSS nodes to get my base SSS material. I have used the method explained in the video tutorial. The color of the SSS node is the base color of the shader. The color of the RGB node is the scattered color. (I should have created a node group with this setup) Also I have added a diffuse node to reduce the noise of my material. Finally I have added some basic glossiness to my material The red plastic is slightly different. Here you can see the node detail: As the SSS materials are very noise, I strongly recommend you to use compositing and bilateral blur nodes to get a good render. You can find some video tutorials explaining this on CGCoockie: Using Blender’s B...

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...

Hi everybody. Today I'm going to show you a simple material, plastic for home or computer appliances. Hola a todos. Hoy voy a mostraros un material simple, plástico para aparatos domésticos o de informática. This is my first approach:  Ésta es mi primera aproximación: The material is basic: a mix between Diffuse and Glossy shaders. I have used a Facing factor for mixing, because I think it works better with this kind of materials which are not very glossy. As you know Facing reflections only are shown when you see the surface in a grazing angles. Also I have added a Voronoi Texture to get a rough effect on the surface. This is the node setup: El material es básico: una mezcla entre shaders difuso y de brillo (Glossy). He usado un factor Facing para la mezcla, ya que creo que funciona mejor para este tipo de materiales no muy brillantes. Como ya sabéis las reflexiones de tipo Facing sólo se muestran cuando ves la superficie en ángulos casi paralelos a ésta. ...
