Hello again! This is a little bit of a necro, but I’m revisiting the issue as my workaround wasn’t permanent and wanted to approach it the way you suggested in your last comment. However I’m left confused because can’t only translucent materials utilize depth fade? I tried looking for a “Camera Depth Fade” node and nothing popped up. I may be daft and just not yet fully understand what was said. This is entirely possible. lol.
Any further explanation would be greatly appreciated. 
edit-
I’ve created something as follows to mimic it. Not entirely certain if this is what you meant, but it’s working to an extent in the material viewport.
edit again! solved. I was being a dork and needed to freshen up on my material editor knowledge a little!
