Shared and seamless gradient effect between two objects? [EEVEE] I've been sitting on getting a flame gradient achieved since I didn't know how to get it to be seamless between two objects. I used very basic mapping, but of course it looks rudimentary:

And here's the screens of both the node sets for the head and the flame:


The flame is a flat plane that uses and image texture, where as the head relies on its own mesh, so I hope it doesn't complicate things.
How can I get a seamless 'universal' texture that will look consistent between both objects?
Here's a mockup to show what I'm aiming at (also ignore the fact there isn't a flame outline, it doesn't matter)
If you use the &quot;Object&quot; output from the &quot;Texture Coordinates&quot; node on both shaders, and then set the origin of both objects to the same location, the seam should disappear.
