Black AOV's in EXR file

[lizGYM66]

I'm exporting AOV's to a multipart exr. When I open the EXR in AE the contact sheet shows the beauty and crptomatte passes, but the other tiles which have the other AOV's in are black. 

I have a separate display driver set to save to .exr with Merge AOV's enabled.

I did a quick test and all AOVs in my EXR were correct. 

Do the AOVs show up properly if you render a regular EXR (Merge AOVs on, but Multipart off)?

I must be doing it wrong. I have a separate driver setup with a few AOVs, set to merge AOV's. When imported in to AE the AOV's are black on the contact sheet. I've tried putting an exposure on them and cranking the value up but it's still black.

Have you tried other viewers? For instance you can open a standard multi-layer exr in Cinema 4D's Picture Viewer, to verify that the content is fine.

It does not support multipart exrs though. Those you can verify with oiiotool from the Terminal. This command splits the multipart exr into separate images, which you can then open in the Picture Viewer individually.
