Step 2 : Anti-Aliasing 4x4 + Global illumination + Color correction


Step 3 : Anti-Aliasing 4x4 + Global illumination + Glow + Color correction


Step 4 : Anti-Aliasing 4x4 + Global illumination + Ambient occlusion (bad setting) + Glow + Color correction


Step 5 : Anti-Aliasing 4x4 + Global illumination + Ambient occlusion (good setting) + Glow + Color correction
