Hello,
I just tried setting up a translucent material with ‘material attributes’ checked and my refraction input suddenly stopped working.
Here’s some screenshots to show what’s happening:
The only difference is the ‘material attributes’ check in the material settings.

this one has been reported for as long as UE4 has been around ( for example Unreal Engine Issues and Bug Tracker (UE-20973) , but was raised long before 2015). it’s a shame since the Material Attributes workflow is otherwise so handy
After ripping my hair out, i recognized now it is still a bug in 4.21 … This needs to be fixed!
I found a similar bug so after searching the forum I found this. I’m using 4.26 and the Refraction issue seems to be fixed when material attributes are enabled, however I’m having problems with a Static Switch Parameter.
Here is the setup I’m using. It is very similar to the problem described, however, the Refraction attribute is working:
I was testing a similar setup in another material where the Switch Parameter is used to turn on or a layer, however, when the material attributes goes through the switch is looses the refraction:
The default value for the switch is False so the refraction index was supposed to be going through.
im having a similar issue in 5.1. I have my refraction set via material attributes in a material function wrapper, but when go at it via a material function, the refraction is lost.
