Ray Tracing Overview - Unreal Engine 4.22 Preview

1- First bad thing about ue4 ray tracing is = not supporting emissive material , second bad thing is dont supporting [not casting shadow] for static mesh , unchecking cast shadow dont work in raytracing

2- Path tracing is unbiased ? So why it has too much noise ?

3- Path tracing dont have denoiser ?

4- Can we see beta raytraced baking in 4.23 ? Because raytracing has too much noise , as architect i prefer to bake light (i love to bake in unreal without lightmaps)

5- in future can we see hybrid raytracing ? Cpu+gpu ? We see offline rendering using cpu for raytracing

6- changing source radius for point lights affect lighting but changing source angel of sun light does not has effect on lighting

7- can we use hybrid lightmass and path tracing ? for example we bake [static]walls and [static]floors with lightmass skylight but we use path tracing skylight for complex objects and set them movable

Sorry for bad English
