oneminus not working in 5.1

Good Evening, for some reason the oneminus node is not working in materials in my 5.1 engine, i am trying to do a render target to put my character on the side of my menu

all working as it should in 5.0.3 as you will see on the image below… i even went and created a project in 5.0.3 made sure it was working and then copied/changed the engine version and ran them both side by side and still 5.1 is not working

Hey @TADSGaming!

I’m going to go ahead and change the category to Bug-Report! This definitely seems like one.

Please make a bug report from in-engine if you can, as well!
