![]() ![]() When using ray tracing, pixel samples and ray sampling parameters must be used to improve surface shading quality. In ray tracing engines, shading quality only affects the geometric subdivision quality for smooth surfaces (NURBS, render as subdivision) and for displacements - without changing the amount of surface shading. A higher value will generate smaller micropolygons meaning that more shading will occur - but the quality will be higher. With all other parameters at their defaults, a value of 1 means that approximately 1 micropolygon will be created per pixel. This parameter controls the geometric subdivision resolution for all rendering engines and additionally controls the shading resolution for micropolygon rendering. ![]()
