Saving EXR Metadata into the VrayOptionsRE

Hello,
We are updating our pipeline to have some metadata from 3ds Max hitch a ride in the .EXR files and while it works great with one attribute and value, when attempting to add a second, it doesnt seem to work? For example, if the data reads
user=philn this works fine when reading the data vie View Matadata in Nuke, however if it reads

user=philn;overscan=false in this case, neither of the attributes comes across? Anyone else run into this?

Fred

Nuke reads them correctly on my end (tested with V-Ray 6, hotfix 2). I basically copy/pasted your code in the EXR metadata slot and rendered. Which V-Ray build do you have installed?
