ERROR : 2004 – Invalid pointer – [line 2]

When you render with xsibatch, you get this error even though the frame does render successfully.

ERROR : 2004 – Invalid pointer – [line 2]

For example:

COMMAND: -render "C:\Users\blairs\Documents\Support\Project\Scenes\Sphere.scn" -
frames 2-4
>Loading: C:\Users\blairs\Documents\Support\Project\Scenes\Sphere.scn...
' ERROR : 2004 - Invalid pointer - [line 2]
' INFO : 4034 - Loaded scene was created with build number: 9.5.184.0 - compatibility version: 900
' ERROR : 2004 - Invalid pointer - [line 2]
OpenScene "C:\Users\blairs\Documents\Support\Project\Scenes\Sphere.scn", False,True
' INFO : Rendering all passes: Passes.Default_Pass
' INFO : Rendering frames '2-4'
' INFO : Rendering pass 'Default_Pass'...
' INFO : Rendering frame 2 (0.0% done)
' INFO : Rendering frame 3 (33.3% done)
RenderPasses "Passes.Default_Pass", , , , siRenderVerbosityDefault

If you running xsibatch from a render manager, this error may cause the render manager to quit the render job.

You can workaround this by renaming the ICEFlow plugin (Application\Plugins\ICEFlow.dll). This plugin manages the transfer of data between Softimage and Maya (the one-click ICE workflow).

Object model methods for finding objects

The Softimage 2011 Subscription Advantage Pack includes new methods for finding objects.

These FindObjects methods are more efficient than X3DObject.FindChildren, because the FindObjects methods don’t go through the scene hierarchy (they go directly to an internal database of objects).

Model.FindObjects( siClassID )
Finds all objects under the model that match a specified class ID (for example, all shaders or all ICE Trees). For example:

 # Enumerate all shaders under the scene root.
 from win32com.client import constants as c
 shaders = Application.ActiveSceneRoot.FindObjects( c.siShaderID )
 for s in shaders:
 	LogMessage( s.ProgID )
 # INFO : Softimage.soft_light.1.0

Supported siClassIDs:
siCameraID | siClusterID | siClusterPropertyID | siConstraintID | siCustomOperatorID | siCustomPropertyID | siEnvelopeID | siEnvelopeWeightID | siExpressionID | siGeometryID | siGroupID | siICETreeID | siLightID | siMaterialID | siModelID | siNullID | siNurbsSurfaceMeshID | siNurbsCurveListID | siOperatorID | siPolygonMeshID | siPropertyID | siShaderID | siShapeKeyID | siX3DObjectID

Application.FindObjects( siClassID )
Finds all objects that match a specified class ID. For example:

from win32com.client import constants as c
oICETrees = Application.ActiveSceneRoot.FindObjects( c.siICETreeID )
for x in oICETrees:
 	LogMessage( x.Nodes.Count )

Supported siClassIDs:
siCameraID | siClusterID | siClusterPropertyID | siConstraintID | siCustomOperatorID | siCustomPropertyID | siEnvelopeID | siEnvelopeWeightID | siExpressionID | siGeometryID | siGroupID | siICETreeID | siImageClipID | siLayerID | siLightID | siMaterialID | siModelID | siNullID | siNurbsSurfaceMeshID | siNurbsCurveListID | siOperatorID | siPassID | siPolygonMeshID | siPropertyID | siShaderID | siShapeKeyID | siX3DObjectID

Model.FindObjectsFomCLSID( sCLSID )
Finds all objects that match a specified CLSID. You can determine the CLSID of an object using XSIUtils.DataRepository () or by inspecting Softimage objects with the SDK Explorer.

# Enumerate all visibility properties under the scene root.
 props = Application.ActiveSceneRoot.FindObjectsFromCLSID( "{11EBE301-A20C-11D0-8478-00A024C7919C}" )
 for vis in props:
 	LogMessage( vis.FullName )
 # INFO : Camera_Root.visibility
 # INFO : Views.ViewC.SpotCamera.visibility
 # INFO : Camera.visibility
 # INFO : Views.ViewB.SpotCamera.visibility
 # INFO : Camera_Interest.visibility
 # INFO : Views.ViewD.SpotCamera.visibility
 # INFO : Views.ViewA.SpotCamera.visibility
 # INFO : light.visibility
