Cine Tracer Full UPDATEDl

path tracer is a lighting method based on rays. the rays are emitted from either a spotlight, a light or a flood light and they move in all directions until they hit a surface. each surface has a reflectance value (normal map or specular map) and a color. when the rays hit the surface they are reflected and diffuse back to the viewer. the amount of surface the rays are reflected depends on the value of that surfaces specular map. when this surface has a specular map value of 1 it produces hard edges and minimal lighting, when it has specular map value of 0 it produces a glass like surface without hard edges and a lot of lighting. every other method involves a shadow map to reduce the sharp edges, the most popular being the lit path tracer.

unreal engine delivers incredible photorealistic visuals, but it requires a powerful machine to handle the processing power needed to render its visuals. you can optimize your system for the path tracer by using the path tracing quality switch node to set the number of bounces to use, which affects the quality of the output. the path tracer uses many more bounces than the deferred renderer to get accurate results, so this node decreases the quality of the image by only using a maximum of the number of bounces in the ray tracing settings.

unreal engine's path tracing features require more ray tracing bounces to achieve high quality, photorealistic visuals than the default approximate bounce/reflection accuracy of 10. decreasing this setting will reduce the quality of the render, but the number of bounces can cause the path tracer to run out of resources such as memory. use the path tracing quality switch node to set the number of bounces to use in the path tracing settings. higher numbers of bounces should be used for increased performance, but lower numbers should be used when rendering quality is more important.
