Are you sure there's anything in the file's RenderLayer.UV channels
besides zeroes? The file reads fine in exrdisplay: no errors
detected during decompression (meaning the pixel data decompress to
the expected size), and all the other channels contain what looks like
a reasonable image. exrdisplay says that the channels in the UV layer
contain only zeros (not random data as you'd expect if the file didn't
decompress properly).
As far as the IlmImf library is concerned, the UV layer is no
different from all the other layers; I'm not sure what kind of bug
would affect only the UV layer, but not any others?
Have you tried saving the file out with a different compression
scheme, or with no compression at all?
Thanks for taking a look at it, Florian. I could have sworn the
channels were full of data, but in your analysis there's no room for
mistake. I tried redoing the render but I don't have any earlier
openexr installed anymore. And the file is from blender and I am unsure
how to check the UV maps in that application.
Sorry for being a bother and reporting a false bug. I apologize.
