Today Adobe released a major update to After Effects and the rest of the Creative Cloud suite. This new AE ships with version 1.9 of the ProEXR plug-ins, which have been available here in beta form. Well, if the plug-ins are good enough for Adobe to ship them, I guess they're good enough for me. Consider version 1.9 released.
The biggest change in 1.9 is that the After Effects plug-in now handles displayWindow natively. Most users will not be affected by this, but the beta notice has more information for those interested.
The other subtle change is that all the ProEXR plug-ins are now built using OpenEXR 2.1, which supports multi-part files and deep image buffers. ProEXR can now read files that use these features, although the files you write will still be single-part flat images that are compatible with EXR readers that haven't yet upgraded.
Even if you're using an older version of After Effects, you can still download the latest ProEXR plug-ins and install them with your copy. Likewise, the Photoshop and Premiere plug-ins will work just fine in older versions of those programs.
As usual, this update is free and recommended for all ProEXR users. Enjoy!
