Pros and Cons of Final Gathering

Final gathering has advantages and disadvantages:

Advantages

• Because it uses fewer photons, scenes render faster and use less memory when creating the Photon Map.

• Final gathering is more accurate than a direct photon map lookup. Accuracy is most noticeable on the edges of objects and in corners.

Disadvantages

• If you do not use global illumination, photorealistic results take much longer to render.

• When using global illumination and high Accuracy settings, the render can take longer than it would without final gathering; however, the slower the render, the higher the quality.
