The VRayOSLMtl material can be used to load OSL shader code files (.osl) or OSL object code files (.oso) and render them directly with V-Ray.
The VRayOSLMtl plug-in can be used with shaders that use closure color output parameters. See the OSL Support page for more detailed descriptions and examples for writing an OSL shader in V-Ray.
Use the Quick Shader area to manually edit the shader's code.
