Hi all,

Getting to grips with python here. Well almost.
I'm following a "trivial example".
Created a Nurbs plane and attached a Pre-Geo Mel Script as follows. I've tried to put in what I've seen on the forum here and in the manual. I'm on Windows 64.

//////////////////////////

Procedural "RunProgram" ["C:\python26\python.exe C:\Users\luke\Documents\maya\2012-x64\scripts\createSphere.py" ""] [-1 1 -1 1 -1 1];
RiAttribute -n "visibility" -p "camera" "int" "0";

///////////////////////////////

the createSphere.py script is as follows

///////////////////////////

# createSphere.py
# Description - make an RiSphere

import sys
sys.stdout.write('Sphere [3 -3 3 360]\n')
sys.stdout.write('\377')
sys.stdout.flush()

//////////////////////////////////////
RIB options output in 0s
// Error: ...L_getAllGeoAttribsNodesFromShape |nurbsPlane1|nurbsPlaneShape1 "";
tHighestAttrNode("shaderCollection", $passes);
Layout|AEcont //
// Error: Syntax error //
// Warning: error in Pre Geo MEL Script in delightGeoAttribs1 attached to |nurbsPlane1|nurbsPlaneShape1
//

Thanks for an advice.

1st - this is not a MEL statement, so try RiProcedural - this might work:

Code:

RiProcedural -pn "C:/python26/python.exe C:/Users/luke/Documents/maya/2012-x64/scripts/createSphere.py" -p "" -b -1 1 -1 1 -1 1;

If you get past MEL errors, see how it goes at python side.

PS. why setting visibility attr after RunProgram ? mistake ?

hey thanks that works,
instead of the RiAttribute I switched off the 'output geometry' in the geo attribute.
I had followed the renderman courseware example where they had the RiProcedural in the 1st line and the RiAttribute in the second line.

thanks again ogre
