OSL
What is it about?
This page documents the OSL node of the Redshift renderer in Cinema 4D. It runs Open Shading Language scripts — written inline or loaded from files — opening the material system to custom, renderer-portable shaders.
OSL stands for Open Shading Language and allows to write your own shader descriptions, that can be shared between other renderers that also offer OSL support. OSL scripts can be loaded as files or written directly inside the shader dialog.
You can find out more about OSL on this website: https://github.com/AcademySoftwareFoundation/OpenShadingLanguage and some Redshift compatible OSL shaders here: https://github.com/redshift3d/RedshiftOSLShaders
