Vector3 Property

[TwinSnakes007]

Does anyone know how to read a Vector3 property? No matter what I try, it always returns "None".

This Python snippet creates a Vector_Switch node which has two Vector3 properties. No matter what I set them too, or how I try to access their value, I only get "None".

Code: Select all

from sipyutils import *

app = Application
Application.CreateShaderFromProgID("Softimage.sib_vector_switch.1.0", "Sources.Materials.DefaultLib.Scene_Material", "Vector_Switch")
oMatLib = app.ActiveProject.ActiveScene.MaterialLibraries

for oLib in oMatLib :
	for oMaterial in oLib.Items :
		oShaders = oMaterial.GetAllShaders()
		for oShader in oShaders:
			for oParam in oShader.Parameters:
				log(oParam.Name + ": " + str(oParam.Value))

the property probably breaks the down into the individual x,y,z values and the none value usually indicates that it is returning a collection of items that you need to get the values from directly.

I've tried that, nothing works. I tried passing it to XSIMath.CreateVector3, still nothing.

Tried accessing the X, Y, Z properties directly, that didnt work.

The only thing I get is "None" when I try to read it. I must be missing something.

Hey TwinSnakes007,
There are some parameter types with sub parameters, in such cases you must iterate in the sub parameters in order to get the values

Code: Select all

from sipyutils import si, log

si().CreateShaderFromProgID("Softimage.sib_vector_switch.1.0", "Sources.Materials.DefaultLib.Scene_Material", "Vector_Switch")
oMatLib = si().ActiveProject.ActiveScene.MaterialLibraries

for oLib in oMatLib :
   for oMaterial in oLib.Items :
      oShaders = oMaterial.GetAllShaders()
      for oShader in oShaders:
         for oParam in oShader.Parameters:
            oValue = oParam.Value
            if oParam.Parameters.Count:
                oValue = map(lambda x: x.Value, oParam.Parameters)
            log("{0}: {1}".format(oParam.Name, oValue))

wow...okay...

Thank you soo much! That really helped me alot. I was stumped on that for weeks.
