    Sure, here it is:

    ramp_projection_error.zip

    The file texture is connected by default, but the ramp as described above is in the scene as well and can replace the connection to the projection node to see the discrepancy.

      Hello Mike,

      Thank you very much for the scene.
      Yes there is some difference between Vray vs Software render when Procedural Map is used with Fit Type set to Match Film Gate - but if Match Camera Resolution Type is used such difference is not observed.
      Would it be possible to use Match Camera Resolution instead of Match Film Gate type ?

        Well, the problem with using Match Camera Resolution is that you can not decouple the render resolution aspect ratio from the projection camera aspect ratio. This was logged as a bug earlier (see this thread history) and fixed for bitmaps, but apparently not ramps and other procedural textures.

        The main idea here is that we want to be able to project an image AND procedural textures with one aspect ratio as derived from the projection camera, but be able to render with a different aspect ratio from another camera.

        Any idea how easy it will be to get this fixed?

          Hello Mike,

          We're working on the issue with camera projection and procedural textures. What's the version of V-Ray that you use?
          Kind regards,
