could you help me with a problem that tortures me already for a month.
I would like to know how by script to save separately Z-buffer(aka depth, range) and color data when data is rendered.
In this case, what I am looking for is how by script to toggle consecutively RenderLayer -> [Combined, Depth] -> (Channels if Image to Draw) ??? and save color layer into a image file(e.g. PNG) and depth data into OPEN_EXR format, but without rendering the scene again(just using one rendering pass for both).
The only workaround(although non-script) so far was done by “Node Editor” where i have manually toggle the output of rendering [Z, Color] , but it requires two passes of rendering.
Could you help me to resolve the matter.
P.S. (Since I am using open source library of EXR reader solution, I would not like to save both Z-buffer and color data together into a single file, because my “libre-source” software does not distinguish when more than 3 channels are saved(as it is a existing option for EXR files).
