OctaneRender® for Blender

OctaneRender® uses Greyscale Vertex attributes while rendering materials. OctaneRender® loads and interpolates real numbers and greyscale shades over the triangles in the scene and provides them to the OSL shaders. Other practical uses would be to create a Vertex Group and use that Vertex Group as a mask for a Mix material (figure 1).
