Help Needed - Substrate Glass Appearing differently between Preview and Scene

Hi all,

Running into a weird thing with UE 5.7. I’m trying to make better materials, and the glass specifically is giving me a bit of trouble with substrate. I switched to Substrate because having a polished glass that’s also blurred and slightly opaque wasn’t working without it. I’m learning this all on my own - so I’m combining various tutorial methods and it’s probably not the most efficient process.

For this one specifically - I’m seeing the glass behave correctly in the node graph and preview, but when I apply it to an object in the scene, the blur is not behaving correctly. The outer surface is showing a blur, but the elements inside aren’t blurring. I’ve included screenshots below of what I mean.

I’m guessing I don’t have a project setting applied correctly, or something in the blend mode isn’t working right. Any tips would be greatly appreciated.

Thanks!
