BTW, does any body knows how to put channel reference to parameter with script, not by hand? Simple:

opparm myObject myParam ‘ch(“someParam”)’

doesn't work. I thought that -r option in opparm is for that, but I was wrong.


thanks!

Channel references can be set by hscript as follows:

chadd myObject myParm
chkey -t 0 -F ‘ch(“someParm”)’ myObject/myParm

eg.

chadd geo1 tx
chkey -t 0 -F ‘ch(“ty”)’ geo1/tx

A good way to figure out things like that is to use the opscript command on something like a geo node with a channel reference set on one parameter.

Alternatively, using HOM it can be set by:

hou.node('/obj/geo1').parm('tx').setExpression('ch(“ty”)') or
hou.node('/obj/geo1').parm('tx').set(hou.node('/obj/geo1').parm('ty'))

Thanks grahamt for your explanation.

cheers,
