Windows 7 x64, Quadro 2000
Worked: 2.74, maybe also 2.75
Short description of error
When I output my files into openEXR using a file output node, I only get black renders. The Alpha Channel is correct however. Output to PNG works fine.
Exact steps for others to reproduce the error
Download the file, open it and render. The file Output Node which outputs the PNG works as expected, the OpenEXR one always outputs a black image.
