I'm using 2.79 and Cycles render.
I'm making a flat, cartoony scene, and would like to essentially use the below image as a horizon/sky texture. I want the image to display undistorted by perspective, independent of the camera/view angle.
I attempted to do this using the World tab > image texture, but I couldn't get it to do anything like what I wanted (under most settings it just shows flat colours from the image rather than the full thing, and one setting gives a kind of distorted polar coordinates-style effect, which is again different to what I'm going for)
I have tried using textured flat planes and cylinders, but these were both hard to set up within the camera view in the way I wanted, and ended up distorting the image texture.
Sorry if this is a basic question - I have tried searching for tutorials on this but nothing I found answered my question, perhaps because I don't know the proper name for this technique.
Thanks in advance!
