What is OSL in Blender?

Open Shading Language (OSL) is a shading language developed by Sony Pictures Imageworks for use in its Arnold Renderer. It is also supported by Illumination Research’s 3Delight renderer, Otoy’s Octane Render, V-Ray 3, and by the Cycles render engine in Blender (starting with Blender 2.65).

What does Open Shading Language do in blender?

The real strength of OSL is the ability to write your own shaders. You can create materials, lights, displacement or patterns in the OSL language itself.

How do I add a shader in Blender?

OSL was designed for node-based shading, and each OSL shader corresponds to one node in a node setup. To add an OSL shader, add a script node and link it to a text data-block or an external file. Input and output sockets will be created from the shader parameters on clicking the update button in the Node or the Text editor.

Where is the OSO bytecode stored in Blender?

With the Internal mode, a text data-block is used to store the OSL shader, and the OSO bytecode is stored in the node itself. This is useful for distributing a blend-file with everything packed into it.

When to use a node group in Blender?

For use in production, we suggest to use a node group to wrap shader script nodes, and link that into other blend-files. This makes it easier to make changes to the node afterwards as sockets are added or removed, without having to update the script nodes in all files.

How are input and output sockets created in Blender?

Input and output sockets will be created from the shader parameters on clicking the update button in the Node or the Text editor. OSL shaders can be linked to the node in a few different ways.
