In this demo @ 1:23 they demonstrate Realtime caustics as feature of RTX, i have been searching for a way to get this effect in my project with no luck at all.
i have all rtx features working properly but i can’t find any option to enable caustics, There is nothing also about caustics in the documentation
Translucent objects just cast raytraced shadows as opaque, and reflective objects doesn’t reflect lights rays to appear on other opaque objects like in the demo
i have UE4.22 official release
Any idea how to get this feature ? is there a special branch that have the caustic feature ?
