Houville :: customising node attributes

Create a text file called "OPcustomize" in your houdini16.0 (or corresponding) folder. Here you can describe the new defaults you want to use with your nodes. For colours

opdefaultcolor Sop null 'RGB 0.0 0.0 0.0';
opdefaultcolor Sop dopnet 'RGB 0.5 0.0 0.0';
opdefaultcolor Sop dopimport 'RGB 0.5 0.0 0.0';
opdefaultcolor Sop object_merge 'RGB 0.475 0.812 0.204';

Thanks to Amber for this one.

Going beyond this:

We can grab the type from a python shell with drag-drop then append ".type()". And we can also work with default and user-defined shapes, and grab the colour info.

# good if you manually selected a new shape.
n.userData("nodeshape");

# good for finding the session default shape for the node
n.type().defaultShape();

# for getting the colour that has been user assigned
n.color()

Example:

opdefaultcolor Driver null 'RGB 0.478 0.478 0.478';
opdefaultshape Driver null 'circle';
opdefaultcolor Driver merge 'RGB 0.65 0.65 0.65';
opdefaultshape Driver merge 'circle';
opdefaultcolor Driver geometry 'RGB 0.145 0.667 0.557';
opdefaultshape Driver geometry 'tabbed_left';

opdefaultcolor Driver gridmarkets::render_submit::1.5.2 'RGB 0.45 0.12 0.6';
opdefaultcolor Driver gridmarkets::nuke::1.19 'RGB 0.976 0.78 0.263';

opdefaultcolor Driver gridmarkets::transcode::1.8 'RGB 0.25 0.5 1';
opdefaultshape Driver gridmarkets::transcode::1.8 'wave';
opdefaultcolor Driver ifd 'RGB 1 .976 0.666';

opdefaultcolor Sop null 'RGB 0.0 0.0 0.0';
opdefaultcolor Sop dopnet 'RGB 1 0 0';
opdefaultcolor Sop gridmarkets::cloud_cache::1 'RGB 0.145 0.667 0.557';
opdefaultshape Sop gridmarkets::cloud_cache::1 'tabbed_left';
opdefaultcolor Sop file 'RGB 0.616 0.871 0.769';
