Hi. Today I'm going to deal with a new node: Vector Transform. It allows to change coordinates between different spaces, World, Object or Camera. If you want further details about coordinate spaces you can check Blender 3D: Noob to Pro . This node offers new posibilities for materials and textures. Every texture in cycles has a Vector input to set the coordinate space for texturing and there is a Texture Coordinate node available which offers several possibilites. By default Generated coordinates are used. Before this node appears in Blender 2.69, we have some problems with textures in Cycles. If we have several objects in our scene with different sizes and they are sharing the same material, with any kind of texture or pattern in it, it is very difficult to set the appropiate scale factor to get the same size of the pattern/texture in all of them. Look this example using Generated coordinates, which uses the Global / World space: All these objects have scales a...

Hi everybody. Today I have done a reference of the new node Blackbody. This node produces a range of colors according to the temperature of a body . It comes from a physical theory which explains that the color of the radiation doesn't depend on the shape or composition of the body, only in its temperature. This node is useful to set emission color for materials: bulbs, lamps, sky or sun. I have used two node setups in this reference (you can see 6000ºK to see the difference): A. Emission Setup: It is a simple setup, with lower strength for camera rays. So you can appreciate the light from the object in a dark scene. B. Lamp Setup: I have added glossiness to the material and mixed with Emission to get a material similar to lamps. This is the bulb node group included, useful for lamps: EDIT: You can download all these materials in blendswap . Black Body Lights reference: 1900ºK Candle 2500ºK Bulb Tungsten 2900ºK Bulb Tung...
