Greyscale Vertex Attribute
OctaneRender® uses Greyscale Vertex attributes while rendering materials. OctaneRender loads and interpolates real numbers and greyscale shades over the triangles in the scene and can provide them to the OSL shaders. This node differs from the Color Vertex Attribute node by reading data primarily from either vertex groups or vertex weight data as opposed to vertex paint data.
