I don’t understand the logic here:

Can someone please explain?

UV Project actually takes the generated texture proportions of an object, not it’s UV. I normally use an empty to project the textures.

How do you get proportions from an empty? By just adjusting it’s x and y scale?

So, I wonder if what I actually want is the “data transfer” modifier instead, but I can’t find an mention of UVs in its interface.

“How do you get proportions from an empty? By just adjusting it’s x and y scale?” - yes, that’s what I do.
