Hello,
we just updated to UE 5.4 and unfortunately there is no more possibility to pick Standanlone Ray Traced Reflections in Post Processing Volume.
As we are working on Hard Surface Product Visualizations im wondering if there is any chance to get those real Ray Traced reflections back in 5.4 or is this from now on the past?
thank you all for your tips and answers!
Greetings
Leon
it’s all integrated into lumen. just use that.
cant manage to make it look as in the old standalone raytracing, reflections defentitely look worse.
any tips how to set things up?
thank you
Lumen with HW RT + hit lighting is true raytracing.
Perhaps if you can describe a specific quality issue you’re having, someone may have a suggestion.
added notes:
if you have connecting raytraced surfaces in close proximity it’s a good idea to disable “lumen reflection screentraces”.
5.3.2+ has a “reflection lightingmode 3” cvar (that is not exposed in the ppv) that will disable the surface cache in reflections, reducing noise. it improves reflection quality if your scene design is well lit, but has the caveat that the “fake gi” in the reflection should be controlled with the skylight as a global ambient boost. be aware it will change the lighting in the real (not reflected scene) too.
if you require volumetric fog in your scene there’s a cvar to “sample fog” in the reflected scene. currently it fogs the reflection properly, but overfogs the real scene.
hope it helps to squeeze.
