Outline Postprocess - Screen Is covered

Hey forum~

I’m doing a 3 week minimal viable product demo for a game, but my progress is being impeded by this one material I made.

Using tutorials I am trying to get an object to have an outline through other objects as these crystal shards are going to be main objectives around the city.

My issue is the following: Despite adding a Subtract where I know I needed to, the objects work perfectly, but the entire rest of the scene is whited out (or blacked out depending on the value of one of my constants)…

I have to figure out how to keep the current effect, but remove the excess alterations. Here’s a pic of the glitch:

and here’s the blueprints I’m using for that material. Keep in mind I have render custom depth and blendables enabled in post process.

that last lerp is plugged into emmision

Any help much appreciated. Sorry if this is a dupe, I checked out other similar problems, but their solutions didn’t help. :confused:
