I reproduce the issue, but more investigation is needed to understand where this is coming from.

Solved:
Changed:
```
importer.SetFileName(path1+file8+'.obj')
importer.SetFileNameMTL(path1+file4+'.mtl')
importer.SetTexturePath(path1)
```

The code works like this (I removed the redundant code).
```
self.importer=vtk.vtkOBJImporter()
self.importer.SetFileName(path1+file8+'.obj')
self.importer.SetFileNameMTL(path1+file4+'.mtl')
self.importer.SetTexturePath(path1)#+file9+'.png')
colors=vtk.vtkNamedColors()
renderer.SetBackground2(colors.GetColor3d("Silver"))
renderer.SetBackground(colors.GetColor3d("Gold"))
renderer.GradientBackgroundOn()
renderWindow.Modified()
renderer.UseHiddenLineRemovalOn()
self.importer.SetRenderWindow(renderWindow);
self.importer.Update()
```
**How I remove the picture from the screen?**
I tried
```
self.importer.RemoveRenderWindow(renderWindow);
```
but do not works.

This thread is still open.
I only want to remove this “volume” from the screen. But it is not a volume, I suppose.
Can anyone help?
Thanks.

What do you mean by removing the picture? Clearing the render window to the background?

Yes, clearing the render window. Of that image in particular.

you can try to learn the c++ demo, which is easy to translate it to python. it shows how to get the actor and mapper of the import.
