Note that in this comparison, some materials or lighting effects are not fully supported for the Path Tracer.
For artists and programmers, the unbiased nature of the Path Tracer’s ground truth image makes it invaluable to have built right into the Engine for comparison. It also removes the need for additional third-party software or plugins to generate these comparison results. For artists, it means being able to fine-tune materials and lighting setups more quickly. For programmers, it improves workflow and iteration times when tuning and validating the look of their real-time algorithms for techniques like Denoising.
