Hello,
Ok so this is a relatively short question but I am struggling with it for some time now.
If you have a File Output node and select it in the Node Editor window, under Properties you can change
the file format from PNG to OpenEXR.
The only thing I want to accomplish is to do this in python script.
If I change it manually, the Info window gives me the following:
bpy.data.node_groups["Compositing Nodetree"].(null) = 'OPEN_EXR'
which doesn’t seem to work for me (even if I select the node and set it active, as I would do using the Blender GUI)
Here is the code snippet how I set up my nodes in python
render_layers_node = tree.nodes.new(type='CompositorNodeRLayers')
composite_node = tree.nodes.new(type='CompositorNodeComposite')
depth_o_node = tree.nodes.new(type='CompositorNodeOutputFile')
normal_o_node = tree.nodes.new(type='CompositorNodeOutputFile')
#delete standard socket and add new one
#Images are called depth_#step
bpy.context.area.type = 'NODE_EDITOR'
depth_o_node.select = True
tree.nodes.active = depth_o_node
bpy.ops.node.output_file_remove_active_socket()
bpy.ops.node.output_file_add_socket(file_path="depth_")
depth_o_node.select = False
#same for normal output node
#delete standard socket and add new one
#Images are called normal_#step
bpy.context.area.type = 'NODE_EDITOR'
normal_o_node.select = True
tree.nodes.active = normal_o_node
bpy.ops.node.output_file_remove_active_socket()
bpy.ops.node.output_file_add_socket(file_path="normal_")
normal_o_node.select = False
#connect nodes!
links = tree.links
link = links.new(render_layers_node.outputs[0], composite_node.inputs[0])
link2 = links.new(render_layers_node.outputs[2], depth_o_node.inputs[0])
link3 = links.new(render_layers_node.outputs[3], normal_o_node.inputs[0])
Now the socket of depth_o_node.inputs[0] (and normal_o_node) should have the file format OpenEXR.
Thanks in advance for any answer
