Troubleshooting
Can not see Exr-IO Options Widget when opening an image
In case you have installed in Photoshop other OpenEXR Plugins, it may happen that they get prioritized in the image opening process and take over the import process instead of Exr-IO plugin. It is recommended to uninstall the other plugins or force Photoshop to explicitelly open the desired file using exclusivly Exr-IO. To do this, use “File/Open As…” and pick explicitely the “Exr-IO” as extension, in order to open the file with Exr-IO.
If you are not sure if you have installed other plugins that my colide with Exr-IO, serach in your \Adobe\Adobe Photoshop Version\Plug-ins for “exr” in order to locate and, if needed, remove/backup those.
Does Exr-IO Works on Mac (MacOS)
Exr-IO is currently not supporting Adobe Photoshop on Mac / MacOS Platforms.
Does Exr-IO Works in AffinityPhoto
AffinityPhoto does not have an API that allows us to port Exr-IO to it. Therefore, Exr-IO will not work in AffinityPro.
My cryptomattes all have an unwanted transparency…
Cryptomattes get imported as black and white masked image contents. If you want to have them as masks on a empty, transparent background, please use our free Photoshop Script
Blender image has wrong colors in Photoshop
This “overburn” look comes from filmic tonemapping in Blender. You can convert your Blender image, rendered with Filmic tonemapper, via OpenColor-IO plugin in Photoshop. Or you can do it on the compositor, in the newer version of blender with a converter node. The most secure way to get exact result in Photoshop is to use Standard tonemapper in Blender. This way, Filmic Color-Profile will not be saved in the EXR File and it will not be wrongly interpreted in Photoshop.
