The ideal :
1> setup scene
2> stereo->Enable. rightFilter->WHITE. leftFilter->WHITE. Animation Tab->Output folder "c:\MyRender". Render
=> The animation render save frameR00001.png AND frameL00001.png
- in "anglyph" current stereo mode it seems that octane render the 2 eyes with a color filter at Sample/2 and mix the 2 render in one picture
so, 2 solutions (choose the most easy to implement in first step)
1> if it's easy for you to disable the second simultanate render which is invisibe, so i think you can just do that with a mod like :
THEN not render this one"
2> if it's easy for you to put an instruction before octane mix the result of RightFilter and leftFilter, OR if (like i suppose) the left and right filter result are in sparate Image Variable, then may you can do a mod like :
"if RightFilter.Color==WHITE AND LeftFilter.Color==WHITE
RightFilter.RenderResult animation Saved in "Frame"+"R"+"Extenstion"
LefttFilter.RenderResult animation Saved in "Frame"+"L"+"Extenstion"
I don't know how is build the octane render plugin, but i think/suppose that RightFilter.RenderResult and LefttFilter.RenderResult are some BufferedImage variable before mixing, so i think it's easy at the end of the render to push a condition (RightFilter is white && Leftfilter is white) to call a function SaveTheBufferedImage with a modified filename.
I hope it's more evident
Note 1: i don't think you have to necessarly disable the current save process. The animation can continue to save the mixed filter results in frame[sequence].[ext], but just add that if a filter is white, he is saved in frame[filtername][sequence].[ext]
Note 2: you can push the concept without the Filter Color condition, because "anaglyph" workers will enjoy the possibility to work on each filter result speparatly (ex: frameR00001.png is blue, frameL00001.png is red) . So, you can just add a CheckBox "Save separate filter (animation only) : True|False " , so whatever the color of the filter, all the stereo-workers will love you like a god for this ultimate-power-time-saving-checkbox !!
