Hi there,

I'm looking at having a little function in Houdini that pre populates the “Output Picture” for Mantra nodes and “Filename Prefix” for Redshift nodes (based on scene location).

…I'm essentially after a way to edit the paramaters using python..

Will Houdini allow me to do this? …anyone know?

Cheers

Sure, just open up a python shell and drop the Mantra or Redshift ROP into the shell window. You will see the full path to the node displayed. Simply assign the hou.node() to a variable and you can read and write the parameters of the node.

Cheers.

For anyone else who may stumble upon this thread, here's how I did it:

output = "//server/my_special_location/$FILM`_`$SHOT`_`$VERSION`_`$OS.$AOV.$F6.exr"
for outNode in hou.node("/out").allSubChildren():
    ROPNode = outNode.type().name()
    if "Redshift_ROP" in str(ROPNode):
        ROPNodeName = "/out/" + str(outNode)
        hou.node(ROPNodeName).parm("RS_outputEnable").set(True)
        hou.node(ROPNodeName).parm("RS_outputFileNamePrefix").set(output)

Hello,
i'm rendering a sequence with some AOVs.
I would like to export each AOV as a separate sequence instead of having all in one multilayer exr.
The issue is that In the filename I'm getting the AOV description after the sequence number witch naturally gives me problems when importing in Fusion.
Any idea ho to solve this?
