How can you automate BlendMode.LINEARDODGE on a 32bits/Channel image?

Question

Hello everyone,

I have a stack of rendered images that came from a cg package that i'd like to create some automation for via layer blending.

The images are currently 32bits/Channel (think of them as several HDR images on layers).

I am trying to combine them using Blend Mode Linear Dodge (Add) through automation to control various lighting sources in a post process fashion.

I can get the automation to work if I am in 8 bit mode, or 16 bit mode, but I cannot automate via 32 bit. I can however manually set the blend mode via point and click in the interface while in 32 bit mode.

I am game for any style of automation that will do it.

If you have CC, you can download CS6 from the Creative Cloud App as a previous version.

Great news,

I updated to CC 2015 and the script runs perfectly. woot woot. Crisis averted. Thanks for the suggestions everyone!

I forgot to mention here is a snippet of the javascript involved.

var doc = app.activeDocument;

var lightBack = activeDocument.artLayers.getByName("Light-Back");

doc.activeLayer = lightBack;

lightBack.blendMode = BlendMode.LINEARDODGE;

The script fails on the last line while in 32 bit mode. Works fine in 8 or 16 bit.
