![]() ![]() When objects are rotated, the output is wrong because the red object should be rendered before the green due to the rotation of the objects. In this case the default behavior for a render engine is to render the first object (green) with a Z position 0.0 first, and then the second object (red) with Z position 1.0 last. ![]() ![]() Sometimes the machine gets “confused” with what should be rendered first and last because it calculates this from what is the center of the object’s Z position.Ī typical example of a Z sort problem is when two colored objects have rotated their Y axis to for example -12.0. The renderer starts by rendering the object furthest behind, and then mixing in objects closer and closer to the camera. To sort objects of a Scene on the Z-axis is essential for any 3D program to render correctly. ![]()
