[vtkusers] prob. with colors in vtkVRMLExporter

[Galen Wilkerson]

Hi,

I am using a vtkVRMLExporter to create .wrl files.

For some reason, everything is either blue or black in the output file.

Does anyone know how to get the VRML output to truly match the VTK 
rendering?  My 3-d objects are not very complex:


 def write_vrml(self,event):
        vrml = vtkVRMLExporter()
        vrml.SetInput(self.renWin)

        vrml_filename = self.abs_file_name + ".wrl"
        vrml.SetFileName(vrml_filename)
        vrml.Write()
        print "Wrote VRML output: ", vrml_filename



I don't think it matters, but the render window is created by using a 
vtkTKRenderWidget:



 self.root = Tk()

 self.vtk_tkrenwigt = vtkTkRenderWidget(self.root, height = 800, width = 
800)

 self.renWin = self.vtk_tkrenwigt.GetRenderWindow()



thanks,
Galen Wilkerson
