Hello,

I’ve just exported a project from 5.1 to 5.4, with same project config, same scene.
However I’m not able to have the same translucency reflection, can’t understand why…

This is the 5.1 reflections:

And ths is the 5.4:

I have enabled the high quality translucency reflections in both projects.

Thanks a lot for help !

Well, by modifying the glass material Roughness, I can got the same reflections (or near the same).

However I would be curious to understand what’s happening exactly with 5.4 and why, if someone can help?

This is the base material that was used:

By removing this and just set 0.01 to Roughness I got back the reflections.

Thanks a lot!
