Problem summary When rendering a script containing two identical RotoPaint nodes that are merged, there will be different results when rendering on different machines if one is using terminal only to render.
This issue only occurs when a script is open only through terminal on a machine that the script was not generate or opened on.
Customer reported version 11.3v3
Customer reported platform CentOS 7
Steps to reproduce
1) Open the attached script
2) View the result through the Write node and render frame 1018 to the preset location.
3) Read the render back into the script and save.
4) Open the newly rendered script in terminal on a different machine using the following snippet (replacing the bold areas with the appropriate information) "C:\Program Files\Nuke11.3v5\Nuke11.3.exe" --safe -t -X Write2 -F 1018 /path/to/script
5) Open the script and the terminal render on the machine the script was generated on and compare Result: The renders produce different results between machines.
Expected behaviour The renders should be identical, irrelevant to how it is rendered and on a different machine.
Actual behaviour When rendering in terminal on another machine, the results differ to the original machine.
Workaround Avoid rendering a script with the above scenario via terminal on a separate machine. As an alternative you can render via the GUI or open the GUI first, then render via terminal which has been proven to resolve the issue.
