Don’t forget that multi-layer EXRs have higher read overhead than single-layer 
files do, since layers are scanline-interleaved within the EXR file itself.

Until everyone starts using EXR 2.0 (including Nuke’s exrReader), separate 
sequences is still the more efficient option.

Subject: Re: [Nuke-users] Trouble Importing my EXR with Layers

What I gather from your post is that you have rendered to multiple EXR's 
instead of one EXR with layers. This is actually my prefered way of doing it as 
a multichannel EXR requires you to shuffle out the layers anyway (unless you 
want to specify what layers to merge in every merge node eg.) 

If you are using V-Ray you pick exr (multichannel) as your output to get 
multichannel exr.

My prefered way is to just drag and drop the folder containing the rendered 
images into nuke, nuke will automatically identify the sequences and you are 
good to go.

  Can you actually describe the problem? 
  What does 'S?' mean?

    Hey, Ive just rendered out all my layers in maya such as the ligths, 
diffuse, specular etc etc, but when I try and bring them into nuke I have to 
make a read file for each individual pass because for some reason it wont 
import a single EXR sequence with layers. 

    How do I get around this :S? 

    any help is greatly apreciated!!
