I have been trying to make use of a camera facing texture in a material for a while. I have done some research and found a lot of people going for a similar effect, but never exactly what I am looking for.
The idea is to have a texture face toward the position of a camera, but unlike a screen space texture, be unaffected by the rotation of the camera. Also, only that specific texture should be camera facing, not the whole mesh or a plane the texture is displayed on. For this reason, I do not think sprites or billboards are what I am looking for.
I have created two gifs in 3DS Max to explain what I want to accomplish. The mesh that the texture would be displayed on is represented by a cube, and the texture is represented by a checkered plane. In a real scenario with the intended result, the texture would be projected onto the mesh, and not be a plane floating between the camera and the mesh. It would be a set of UVs for the material displayed on the cube.
As you can see in this first gif, the texture behaves similarly to a screen space texture.
However, in this second gif, you can see that it is not exactly like a screen space texture, since it is unaffected by the rotation of the camera.
I would like to know how to accomplish this result in unreal.
