Several "Color">"MixRGB" nodes to do the actual blending pairwise. Remember to connect their "Vector" input to the "UV" output from the Texture Coordinate node You will need:Īn "Input">"Texture Coordinate" node, and its "UV" socket to obtain information from the object's UV mapĪs many "Texture">"Image texture" nodes as your layers. Then create a new material and open the Node editor window.Īdd new nodes by clicking "Add".
In the UV/Image editor window, open all the images that you will need as layers I've done this by selecting it (in my example, half a cylinder) in edit mode and hitting U. Select your object and assign an UV map to it. To create a textured material for Cycles whose ( 2D) texture is obtained by blending different layers, you can follow these steps. You're looking for a way to fake this behavior, then my answer isn't byĪveraging the colors of different layers. In principle, you can't make two distinct objects "blend" theirĪppearance in the 3D scene through 2D blending modes, i.e. Translucency, diffusion etc, in a way that is meant to be faithful to Materials, that can be comprised of reflections, refraction, That hits the camera depends on its path through the scene's In the 3D raytraced rendering, the color and intensity of each ray World, but either on the 2D space of a surface's material or on the (I understand the tools are very different, and I do know how Nodes and materials work pretty well.)īlend modes are implemented in the Color>"MixRGB" node, and are almost the same as in any layered 2D graphics software, like Photoshop or Gimp. How would I try different Blending modes for 2D layers or meshes as can be done in Photoshop? How many different Blending Modes can be produced, and how? I could only find this reference online, which seems obsolete and whose links are broken. Say I want to "fake" smoke with a 2D alpha layer, or use a Color Dodge blending mode for a mesh, how would I proceed? However, I am trying to understand how this works better.
The Compositor can also be used, but usually applies to the whole image outputted (if I understand correctly). In Blender, transparency is usually done in the Cycles render engine, in the form of shaders applied to a material or an imported image. These are the different Blending Modes in Photoshop: Here's an example of a composite image made with Blending Modes: The user can quickly cycle through different Blending Modes with a keyboard shortcut. In Photoshop and some other image editing programs, Blending modes allow you to composite images by creating various types of transparencies that adapt to other layers.
