hi,

When i study some otls , they are often very complicated ,and i want to know which node reference some parameter.

Is there an easy way to find all child nodes that referenced a special otl parameter ?
thanks!

Rightclick on parameter (or even whole node)/View Dependencies…
sometimes it's in More/View Dependencies…

there you can see what is dependent on the parm/node and what it is dependent on

you can as well turn on dependency links in Network Editor
Network Editor Display Options/Dependency
