OpenEXR : BitmapIO - Render Elements - Enable State

[Dan.Sambell]

Hi All,

I have hit a bit of a hurdle regarding the OpenEXR : BitmapIO and automating the configuration via MAXscript. 
I am trying to automatically add all of the user created V-Ray Render Elements to the EXR file format via MAXscript for purposes of submitting a series of renders through the Batch Render tool. 

Below is the code I am using to achieve this:

re = maxOps.GetCurRenderElementMgr() -- get the current render element manager

for n = 0 to (re.numrenderelements() - 1) do
(
el = re.getRenderElement n
exrSettings.addRenderElementLayerRef el (el.elementname as string) 0 0
)

I am able to successfully add all of the V-Ray Render Elements to the OpenEXR : BitmapIO however their state is defaulting to "Off". Does anyone know how to enable/turn on each Render Elements state within the OpenEXR : BitmapIO via MAXscript?

I have looked through the MAXscript docs such as the following:

However I have been unable to solve this issue. I assume it is going to be something extremely simple that I have overlooked but none the less, I would greatly appreciate some help in pointing out my oversight.

Cheers,

Biznitch
