The wasteland door asset can be seen propped up against the wall on the center left of the Nova Prospekt trailer thumbnail :)
Half-Life 2 RTX is a community-driven project by Orbifold Studios, a collective of modders, developers, and hobbyists. The goal is to use RTX Remix, which is a sophisticated but user-friendly middleware that's capable of proper raytraced remasters of classic games. Since it's a community effort, all contributions are voluntary—there’s no pay involved, but for true Half-Life fans, it's more about passion than anything else. That beind said, my time working on this has been extremely limited so far, so I do not a lot to show as of yet.
