Here is my JScript example rewritten in Python:
##--------- start of script (Python) -----------
from win32com.client import constants as xsi;
#--------------------
# Constants class
#--------------------
class Constants :
INDEX_SHADER_PORT_TYPE = 0;
INDEX_SHADER_PARAMETER_TYPE = 1;
#--------------------
# GetShaderParameterInfo()
#--------------------
def GetShaderParameterInfo( oObject ) :
oConstants = Constants();
if not oObject.IsClassOf( xsi.siX3DObjectID ) :
return;
oMaterial = oObject.Material;
oShaderParameter = oMaterial.Parameters( "surface" ).Source;
if ( oShaderParameter ) :
oShader = oShaderParameter.Parent;
LogMessage( "Shader: " + oShader.FullName, xsi.siComment );
oParameters = oShader.Parameters;
for oParameter in oParameters :
aParameterData = oShader.GetShaderParameterType(
oParameter.ScriptName );
if ( oShaderParameterType[ oConstants.INDEX_SHADER_PORT_TYPE ] ==
True ) :
# input parameter
LogMessage( "INPUT: " + oParameter.ScriptName + ", " + str(
aParameterData[ oConstants.INDEX_SHADER_PARAMETER_TYPE ] ), xsi.siComment );
else:
# output parameter
LogMessage( "OUTPUT: " + oParameter.ScriptName + ", " + str(
aParameterData[ oConstants.INDEX_SHADER_PARAMETER_TYPE ] ), xsi.siComment );
return;
#
GetShaderParameterInfo( Application.Selection(0) );
##------- end of script -------------------

You need a reference to the shader object, then use it's methods to test each
parameter as shown here:
//-------- start of script (JScript) --------
var INDEX_SHADER_PORT_TYPE = 0;
var INDEX_SHADER_PARAMETER_TYPE = 1;
GetShaderParameterInfo( Selection(0) );
function GetShaderParameterInfo( oObject )
{
if ( !oObject.IsClassOf( siX3DObjectID ) ) {
return;
}
var oMaterial = oObject.Material;
var oShaderParameter = oMaterial.Parameters( "surface" ).Source;
if ( oShaderParameter ) {
var oShader = oShaderParameter.Parent;
LogMessage( "Shader: " + oShader.FullName, siComment );
var oParameters = oShader.Parameters;
for ( var i = 0; i < oParameters.Count; i++ ) {
var oParameter = oParameters(i);
var oShaderParameterType = oShader.GetShaderParameterType(
oParameter.ScriptName );
if ( oShaderParameterType.getItem( INDEX_SHADER_PORT_TYPE ) == true
) {
// input parameter
LogMessage( "INPUT: " + oParameter.ScriptName + ", " +
oShaderParameterType.getItem( INDEX_SHADER_PARAMETER_TYPE ), siComment );
} else {
// output parameter
LogMessage( "OUTPUT: " + oParameter.ScriptName + ", " +
oShaderParameterType.getItem( INDEX_SHADER_PARAMETER_TYPE ), siComment );
}
}
}
return;
}
//--------- end of script ------------

hi dan
unfortunately this gives an error:
# ERROR : Traceback (most recent call last):
# File "<Script Block >", line 79, in <module>
# if ( i.PortType == 0 ) :
# File
"C:\Autodesk\Softimage_2015\Application\python\Lib\site-packages\win32com\client\dynamic.py",
line 516, in __getattr__
# raise AttributeError("%s.%s" % (self._username_, attr))
# AttributeError: <unknown>.PortType
# - [line 79]
i can't wrap my head around that. is there a wrong context?
if i print oNode i get:
# Sources.Materials.DefaultLib.Scene_Material.Phong

hi matt
thank you
i tried to translate to python:
this part works and prints:
for i in oNode.Parameters :
oNodeParameterType = oNode.GetShaderParameterType( i.ScriptName )
print oNodeParameterType
# (True, 1)
# (True, 3)
# (True, 1)
# (True, 1)
# (False, 4)
now, how to get the first thing? (true/false)
this does not work:
for i in oNode.Parameters :
oNodeParameterType = oNode.GetShaderParameterType( i.ScriptName )
print oNodeParameterType
if oNodeParameterType.getItem( 0 ) == true:
print i
else:
print str(i) + "OUTPUT"
# ERROR : Traceback (most recent call last):
# File "<Script Block >", line 84, in <module>
# if oNodeParameterType.getItem( 0 ) == true:
# AttributeError: 'tuple' object has no attribute 'getItem'
# - [line 84]
i think i'm close now... i hope so...
