Houdini tiled rendering problems with Image Planes

Recommended Posts

Hi,

We are having issues with tiled renders not writing out the images planes that are present in scene. Doing a local render or non-tiled submission with Afanasy works as expected.

Looking at the tile renders generatedby the job before the stitch, it appears that whilst there is a separate .exrfile written out for every tile named "filename.exr.tile_1.exr" for example for tile #1, this contains no image plane information. We also have a file namedsimply "filename.exr" which does have embedded image planes but seems to be being written to by each node that is rendering a tile, simultaneously and is always unreadable. 

Is this correct behaviour and does Afanasy actually support tiled rendering with image planes in Houdini? I would have thought that each separate tile .exr would contain all of the required image planes for the stitched image.

If you can shed any light on what we may be doing incorrectly that would be appreciated.
thanks
Tom
