Single Layer Water - Specular reflection show "through" objects

[Agint]

This light is behind the cube, but still the specular reflection show in the area shadowed by the cube.

This happens with directional lights too, and happens with all types of reflections set either it is Lumen, RT, or screen space.

Is there a way to avoid this? Do I have any settings wrong? What is going in here?

This type situation happen when casting shadows are off

I think your scalability settings are low
Or cast shadow option is off for the object or the light

[Agint]

Thank you,

What do you mean by scalability settings are low?

Cast shadows are on for both:

I have trid to tick and untick the other options as well, translucent shadows, etc. etc. but nothing helps.

Also, the moment I change the materal from Single Layer Water to the ususal default “Unlit”, it shadows like it is supposed to and the specualr reflection disappear.

these are scalability settings

Ah, yea, choosing Cinematic, problem is still there, so that is not the problem either…

This seems to be an issue with the Single Layer Water material,

Maybe there are some secret box to tick to make this work (as with so many other things in Unreal), I don’t know.

Did you figure this out? I’m running in to this just now.

It was a limitation before, but works now if you use Lumen and NOT ray traced shadows.

Also, these two console commands helps the quality significantly:

r.Water.SingleLayer.ShadersSupportVSMFiltering=1
r.Water.SingleLayer.VSMFiltering=1
