PSD composite - don't match final image

[G0M0]

Hello
I have problem with reproducing rendered image based on render elements.
I use recipe found on various topic:

But there is a difference in images, here is a rendered image:

And composited:

And here is difference between two images:


I've tried both tga composite and exr composite, Photoshop and Autodesk Composite - always the same differences.

Does someone have some ideas?
Thanks in advance for answers.

If its not 32 bit comp then it wont match.

Also as far as I remember blendmtl wont comp correctly or I'm wrong, I think I'm wrong...

I've tried with 32 bit exr files (images are brighter) - the same problem occur.

Try using standard render elements non raw- u using any non vray materials blend etc etc?

[G0M0]

Ok, I'll try.
Only vray material is used.
Thanks

Unfortunately still getting those errors but I've found a some workaround to what I am really up to.

Yup, got same issue. If I remember the only way to fix is is to substracte and create new layer.

Not sure if the issue is due to photoshop being rubish at 32 bit or Vray. See if u can match them in nuke or ae.

What do you mean by "substracte and create new layer" ?

I tried the same thing in Autodesk Composite with the same result.

[Dariusz Makowski (Dadal)]

I mean do the comping as u do, duplicate them all>merge>substract from beauty > merge > and use that as ur fix layer on to of ur comp...

[G0M0]

Ah, you mean to use difference to fix composition?
I know how to extract difference in photoshop but I have now clue what operation to use to achieve inverse effect - opposite of difference.
Trying right now

Reflection>Screen
Specular > Screen
Light > Screen
GI

Merge them all and call it Mergedlayers then

3ds max render - beauty Substract
Mergedlayers
=
data that are missing from ur comp.

Multiply or screen it on top of layers above to fix ur comp.
