Hi everybody,

I'am trying to set up a little helper script in order to manage all my cameras and rendersettings. When I'm trying the script in C4D R12 directly everything works fine.

But when I try to render the scene on our servers with NetRender the clients report the following problem:

File "<Python-Generator>", line19, in main
Attribute Error; 'module' object has no attribute 'RDATA_PATH'

Isn't there any active renderdata when rendering with NetRender? That would be very astonishing.
Does anybody have an idea?

Here's the code:

import c4d
from c4d import documents
#Welcome to the world of Python

def main() :
doc = documents.GetActiveDocument()

rd = doc.GetActiveRenderData()
rdName = rd.GetName()

bd = doc.GetActiveBaseDraw()
rc = bd.GetSceneCamera(doc)
rcName = rc.GetName()

if rdName != rcName:
      bd.SetSceneCamera(doc.SearchObject(rdName+"_kamera"))

rdOutputFilename = rd[c4d.RDATA_PATH]
newRdOutputFilename = rdName+"_"+doc.SearchObject("Namenszusatz")[c4d.ID_USERDATA, 1]+"___"

if rdOutputFilename != newRdOutputFilename:
      rd[c4d.RDATA_PATH] = newRdOutputFilename
      rd[c4d.RDATA_MULTIPASS_FILENAME] = newRdOutputFilename
      c4d.EventAdd()

print newRdOutputFilename

pass

Ok, after updating...
The error message doesn't appear anymore.

But it seem's that there is something strange in my code.
Because now the application on the clients shutdown without any error prompt and the server needs a few minutes to realize when the job was stopped.

Is there something special I've to keep in mind when writing scripts with Python for NetRender?

I've got it.

Setting cache optimizing to no solves the problem.

I keep getting - AttributeError: 'module' object has no attribute 'ID_USERDATA'

That seems to be a bug in NetRender, the identifiers are not loaded correctly.
However, we are still waiting for an official statement, maybe they know a workaround. The only that comes into my mind would be replacing the access to the constant identifiers with their actual value, but that will cause the script to loose platform and version independence.

@mchaloner: Please install the latest update on the Netrender clients. Does the problem still occur?

I'm using the latest R12 NET Render Client, I think! (Build RC32293)

Made a work around that basically dumps all the helper python tags before calling the save project command...

included it if it helps anyone

Weirdly the main app is 12.048 - but my net client is still 12.016.

I downloaded the update from the Maxon website and selected Manual Installation from the NET client...

and I get this

I tried to reproduce this but without any success. But I know the problem was fixed in one of the updates so maybe something is broken with your installation (just guessing).
