Painter is creating not usable 32bit displacement\height files. Solution and request for a fix.

Hello, 

Long story short; I spent 4 hours trying to use in zbrush, edited in painter 32bit .exr displacement map. 
By default zbrush can't load such maps!!! 
To make it work, I had to open it in photoshop, flatten the file and save it. Before that, there was only some weird, single layer.


Please fix it, sims to be super easy.
Thanks!
