How do I see through a solid part of an entity?

I am currently creating a Titanfall mod for Forge 1.20.1. I am working on the Titans, and need a way to be able to see through the front while the Titan is still opaque from the outside, sort of a one-way glass type thing. In Titanfall 2, this is accomplished by turning the inside of the cockpit into a screen that shows the outside, but I have no clue how to do this in MCreator. Any help would be appreciated!
