I've only just recently started rendering out 32bit exr files and I am limited to rendering only on my machine. Submitting to backburner causes problems is which the render will write the file but start over. It ends up overwriting the file in a never ending loop. The Error message I get is: Autodesk 3dsMax 16.3 reported error: Tif Error - Not a Tiff file, bad Magic number 55551 (0xd8ff); Tif- Invalid I. If anyone has a solution I could use some help. Thanks!
