ID 238890 - The Write colorspace is inconsistent across views when multiple views are rendered with OCIO color management.

Problem summary
The Write colorspace is inconsistent across views when multiple views are rendered with OCIO color management.

Only one of two views (rendered as left,right) had the correct colorspace applied.  Need to write each as single view (left or right only).

Customer reported version
Nuke10.0v4

Customer reported platform
Linux

Steps to Reproduce:

1. From Nuke, mouse over the Node graph and press S on the keyboard to open the Project settings.

2. In the Project settings, select the Views tab and click on the Set up views for stereo button.

3. Select the Color tab and set color management to OCIO.

4. Set the Color settings to the following:

    

 

5. In the Node Graph, create two Constant nodes.

6. Change the color of each Constant node to Red and Green, respectively.

7. Add a JoinViews node, and place the left and right inputs to both Constant nodes as follows:

     

 

8. Add a Write node attached to the footage.
     8a. Set the Write node's colorspace to default (ACES-ACES20651).
     8b. Set the file knob's path as an .exr to any location.

9. Render the Write node.

10. Read the .exr back in and view the node.

11. Compare the Write node's left/right views to the newly rendered Read node's views.

Workaround:
Write each view individually (left or right only).

Expected behavior:
The colorspace should be applied to all views when writing an .exr file.

Actual behavior:
An incorrect colorspace is applied to one view when writing both views from a single Write node.
