I've just started using Natron for the first time (downloaded the latest version), and I've found that I'm unable to correctly read my multichannel exr files. They're rendered out of Vray and I've tried a number of compression options yet all I get is black in the viewer. It seems that it sees it as an exr ok as I can see all the channels in the 'output layer' drop down in the read node. Yet none of those channels are seen in the viewer. Any help would be greatly appreciated.
