Hi,
Ok, so after reading the python api, looking on stack exchange and
trying stuff in the console, I am officially out of ideas. I am trying to
understand why it is all the passes from a multilayer exr file don’t show up in
the outputs collection of a CompositorNodeImage type node. The code follows
below, would appreciate any advice for how I could get all the passes to appear
in the outputs collection without having to manually go and hit the refresh
button which is tied to the bpy.ops.image.reload operator. The whole idea of
this script I am writing is to automate this part.
bpy.data.images.load(f,
check_existing=False)#bpy.ops.image.open(filepath=f)
img_n = rl_gp_nodes.new('CompositorNodeImage')
img_n.name = image_name
image_name = os.path.split(f)[1]
img_n.image = bpy.data.images[image_name]
img_n.layer = rl.name
img_n.image.reload()
Manually reloading the image from the Image node properties panel in the node
editor causes the additional passes (defaults seem to be Combined and alpha) to
appear in the outputs for the node, but there doesn’t seem to be any other way
than manually pressing the reload button. image.reload doesn’t work, it does
nothing. running the bpy.ops.imag.reload operator results in it returning
cancelled, I suspect context maybe incorrect here. Still if it does the same
operation as the image.reload then there is little point.
I want to try to automatically load a multilayer exr file into blender and have
all the passes show up for the user to access. I’m doing this for multiple
image tiles of a render coming from another machine so I need a way to automate
this step.
Thanks! :D
James
