Axises orientation#Z up


Blender till 2.76b works on Windows XP



Blender Internal renderer has been removed from 2.8... Blender 2.80 has been released on July 30, 2019

Each row in the Outliner shows a data-block... Shift when clicking on the disclosure triangle will expand child data-blocks recursively... To set parent-child relations between objects, drop an object onto another object while holding Shift.


Material slots link materials to objects and meshes. By default objects only have a single material slot, which assigns a material to the entire object... To apply several materials to different faces of the same object, you use the Material Slots

Blender is built to allow you to reuse anything... reuse an existing material... Only if it has 0 “real” users, and no “Fake” user, will the material be permanently deleted. Note that it will still remain in the Materials list until the blend-file is saved, but will have disappeared when the file is reloaded.

Procedural textures[edit]

Procedural textures are textures that are defined mathematically... are ‘real’ 3D. By that we mean that they fit together perfectly at the edges and continue to look like what they are meant to look like even when they are cut; as if a block of wood had really been cut in two

Shader nodes[edit]

shader socket. The output of all surface and volume shaders is a shader, describing lighting interaction at the surface or of the volume, rather than the color of the surface... Each shader node has a color input, and outputs a shader. These can then be mixed and added together using Mix and Add Shader nodes... In Cycles, custom nodes can be written using the #Open Shading Language... node groups can be used for reusing texture setups... default texture coordinates for all nodes are Generated coordinates, with the exception of Image textures that use UV coordinates by default

shaders available as nodes[edit]

  • BSDF shader

Describe light reflection, refraction and absorption at an object surface.

  • Emission shader

Describe light emission at an object surface or in a volume. Emission shader output can both be plugged into the Surface Input as well as the Volume Input of the #Material output node.

  • Volume shader

Describe light scattering inside a volume.

  • Background shader


Describe light emission from the environment.

This node should only be used for the world surface output


The Holdout shader node is used to create a “hole” in the image

Principled BSDF[edit]

combines multiple layers into a single easy to use node. It is based on the Disney principled model also known as the “PBR” shader, making it compatible with other software such as Pixar’s Renderman® and Unreal Engine®. Image textures painted or baked from software like Substance Painter®

Output nodes[edit]

Output nodes are the final node in every node tree... only one will be used ... Output nodes are always preceded by Shaders except in the case of the Displacement


used to output surface material information to a surface object Inputs: Surface, Volume, Displacement


used to output light information to a light object. Inputs: Surface


used to output light a color information to the scene’s World. Inputs: Surface (The appearance of the environment, usually preceded by a Background shader.), Volume

Open Shading Language[edit]

these nodes will only work for CPU rendering; there is no support for running OSL code on the GPU


Eevee materials are created using the same shader nodes as Cycles... Unlike Cycles, Eevee is not a raytrace render engine. Instead of computing each ray of light, Eevee uses a process called rasterization... it has a large set of limitations

Prefer using the Principled BSDF instead of multiple BSDF nodes

Sky Texture Not supported... Material Output Displacement output behavior is broken compared to Cycles.

Eevee’s goal is to be an interactive render engine... Only perspective and orthographic projections are currently supported... Only 128 active lights can be supported by Eevee in a scene. Only 8 Shadowed sun lights can be supported at the same time... only the needed textures and meshes (now referred as “the resources”)
