I'm having some issues with .exr files.. Still kinda hate this LWF workflow, old way seems so much easier :/
I've made a scene that you can get here if you want: http://www.suurland.com/tests/exr_test/exr_test.zip
Everything is default settings, there is a two planes and two spheres and a vraylight. the plane on the right has "Matte object" checked in its vray properties.
Screen shot:

When rendered and saved as OpenExr as 16bit half float and opened in Photoshop using ProExr it looks like this, which is as expected:

When I paint in some grey under the sphere on the right it looks like what you see below, this is also expected:

When opened in PhotoShop the file comes in as 32bit, but I really want to have a 16bit file as there are varies things that doesn't work in 32bit. So I convert it to 16bit and when I'm doing it I chose don't merge. and I get this result:

Now the shadow from the matte is suddenly a lot darker but everything stays the same, actually the Photoshop grid also gets darker!..
Why is this? How do I avoid it?
If anyone have a perfect way to work with exr I'll be all ears, when I look around every body seem to be doing something different.
