Vray color mapping issue

Ervin

I'm trying to composite a scene with render elements, and no matter what I try, the final result it always off. 

Beauty Render:
EMvunSE

Composite: 
XYqvQm2

It seems like the color mapping may be wrong in some way, but I have no idea what could be causing it. Also this is in 32 bit, if I switch to 16 bit it becomes much worse.

The layers just include Gi, lighting, reflect, refract, and spec, blended with linear dodge

here are the exrs if anyone wants to take a look https://www.dropbox.com/s/u2vc5up6st102tf/1.exr?dl=0

What tool are you using to composite with? Photoshop is notoriously bad at handling color spaces properly.

What 3d software are you rendering with V-Ray in?

photoshop and 3ds max

Don't use Photoshop, if you care about subtle shading differences between composite and render. Sorry. 

Use a proper compositor like Nuke or Flame or even After Effects.

In a pinch you can use the Slate Material Editor in Max as a compositor. Use the Composite map node, and right click on the preview render to choose Render Map to render the final composite. http://help.autodesk.com/view/3DSMAX/2018/ENU/?guid=GUID-A4142EB6-3C08-43FB-83C6-C3C2B1DD2605
