View Full Version : Finding file nodes in shader tree

Hey everyone,

I'm trying to find all the file nodes in a given shading group's network. Right now I'm working on a recursive function to check through all the upstream nodes starting from the shading group, and running into some problems with it. I feel like there's got to be an easier way of doing this though, I feel like I'm missing something.

Do any of you have suggestions as to what I should do differently, I should I just plow ahead with that recursive proc? Thanks in advance for any help!

hey. file nodes are part of a shaders history, so if you do:

listHistory lambert2;

it will list everything belonging to the network "lambert2", which will include all the file nodes.
you can then filter this list for just file nodes:

string $network[] = `listHistory lambert2`;
string $fileNodes[] = `ls -type "file" $network`;

(or my preferred method):

string $fileNodes[] = ls("-type","file",listHistory("lambert2"));
