I am trying to apply an image with a horizon line of a city on a plane.
The face I'm trying to apply it to is like a trapezoid shape.
But when I preview the render in rendered view, the horizon line seems skewed (bottom right preview):
If I change the size of the two vertices on the left in UV image viewer, I get a rendered preview that makes me feel like the plane isn't really plane, and that Blender is adding an invisible edge to deal with this:
I've found this question here "How to flatten a face to avoid distortion (make an ngon planar)", but none of the solutions on this question helped solve it.
Blend:
Note: this model is inspired from the works of Patrick Hughes.
