Bounding Box Image in OpenEXR not being cropped by RV

Hey guys,

I'm having a strange problem with RV, not sure if I'm just missing a function of it somewhere. On our current show we are rendering OpenEXR files with some extra over-scan bounding box image outside the frame. We are using Nuke as our comp package. When I flip the shot RV wants to show me everything including the extra bounding box image. Unfortunately this is eating all my machines ram and I can't flip the complete shot. I can't seem to find the option to have RV just flip the actual resolution of the shot and crop the outside pixels. We are using 3.8.6 release.

many thanks

    Hi Shervin,

    If there is a Data Window specified in the EXR, RV should only load and play that portion of the image.  If the Data Window is bigger than  the Display Window it will load and show you everything, but "frame" on the Display Window.  To prevent loading of the region outside the display window, you can set your own crop (Data WIndow) from the command line.  Suppose the image is 2448x1956, but the display windows extent is 200,200,2247,1755 (xmin,ymin,xmax,ymax), then you can set the crop to those numbers:

    rv [ foo.exr -crop 200 200 2247 1755 ]

    (Note that the Display and Data windows coordinates for exr files are listed in RV's Image Info widget.)

    Hope that helps,
