Transparent objects disapear (EVEE)

I am trying to create some animations for my student pilots to explain instrument procedures. This requires column of air that I am having trouble with. As you can see, the assets come out somewhat correctly from one direction, however are completely opaque in the other. I have Backface culling on, Apha blend mode and none set for shadow.

This is the previous animation sample I did for another procedure and everything worked as planned.

Thank you in advance for any help

resolved :man_facepalming: I had setup the plate material incorrectly.

Glad you figured it out. I just wanted to say your animation is a very cool educational application of Blender. :+1: :+1:
