PDG - ERROR: Cannot find node ...

Recommended Posts

Simply trying to cook a ROP Mantra node inside a TOPNet and repeatedly get the following error

Quote

ERROR: Cannot find node /obj/topnet2/ropmantra1/ropnet1/mantra1

 

when that node definitely exists! What am I missing?

You might want to post the hip file because it simply should work. Also, try recreating the node. It seems there's bug (feature?) with what exactly is evaluated when you press "Cook".

I was having the same problem when I buried a tops manager in a hda node I was creating.  The error showed up for me when I copied my node and tried to run the copy.  Then (30 mins of debug later) I realized while I was creating and testing the task graph, TOPs was previously prompting me to save before running and once it was in the hda I made it wasn't giving me that prompt.  Not only was it unable to fetch the rop, it wasn't getting parameter changes either.  Once I save the file the error goes away and all parameters are updated.  I could be wrong but TOPs seems to be running a new session of houdini for tasks and its using the current saved file.  Makes sense, but isn't obvious while working. 

There is a general problem with TOPs that it doesn't offer much feedback if it's in an hda.   It's own feedback is awesome to watch in the task graph, but there is nothing being sent to a progress bar or the status bar at the bottom, so when it's buried in an hda there is just silence... well my computer's fan starts up... so I know it's working... but otherwise no gui feedback.

Hope that helps, I was pulling my hair out,
