Setting up an Example Look Pipeline

@alexaz

Initial Import

from rv import commands, extra_commands

Get the last source at current frame

source = commands.sourcesAtFrame(commands.frame()[0])

Find the source group

sourceGroup = commands.nodeGroup(source)

Find the look pipe group that is on the source group

lookPipe = extra_commands.nodesInGroupOfType(sourceGroup, “RVLookPipelineGroup”)[0]

Set the order of the look pipe operations

commands.setStringProperty(“%s.pipeline.nodes” % lookPipe, [“LinearToAlexaLogC”, “RVLookLut”, “rec709ToLinear”], True)

Find nodes of type RVLookLUT

looklut = commands.nodesInGroupOfType(“%s.pipeline.nodes”, “RVLookLUT”)
commands.nodeType(lookLUT)

Set the LUT file path on the node you found

commands.setStringProperty(“%s.lut.file” % “/path/to/cube”)
