Ray-tracing

Compared with the development direction of unity, Unreal Engine 4 is more inclined to host games, so epic's game development pursues more image quality and special effects rendering, so many large game companies prefer to use Unreal Engine 4 to develop games. In game development, Unreal is more powerful and more comprehensive than unity in material editing, rendering, and physical systems. Of course, there is also a clear difference in the ray-tracing test of the software. Because by modifying the settings, the Unreal Engine 4's light saturation is also significantly different than the unity. For example,

the following picture:

This is my screenshot of the scene without ray tracing (No.1):

This is my screenshot of scene ray tracing (No.1-low quality):

This is my screenshot of scene ray tracing (No.1-high quality):

This is my screenshot of scene without ray tracing (No.2):

This is my screenshot of scene ray tracing (No.2-low quality):

This is my screenshot of scene ray tracing (No.2-high quality):

If you look particularly carefully, you will find that the change is large between the ray tracing is turned on and off. Before turning on, the light is particularly dim, even without light, but the brightness is obvious after turning on, and the image quality is greatly improved. If further analysis is found, the difference between high-quality and low-quality ray tracing is very huge through the modification of the settings. Compared to low-quality ray tracing, the particles on the high-quality picture are not noticeable and look particularly smooth. And there is another important point. Due to the limited configuration of personal devices, the system will crash when it reaches a certain height, so if there are better devices, the effect can be improved.
