Raytraced Translucency not working in 5.1?

Development Rendering

Hey There,

is it possible that the Raytraced translucency feature is not working in UE 5.1 with Lumen?

Cheers Daniel

Raytraced translucency has never been compatible with Lumen, and likely never will be.

3

Do you now, why this feature will not be added?

4

RT features are in a semi-deprecated state, except for shadows, because they want to focus on developing and improving Lumen.

5

So it could be that they add “Lumen-Refraction” based on Lumen Technology in the future?

That’s my hope. In theory it should be possible. The math for refraction is not significantly different from reflections.
