<br>
Could you try turning interaction off on the renderer you use for your<br>
"foreground" objects. In my code I have:<br>
<br>
auto foregroundRenderer = vtkSmartPointer<vtkRenderer>::<wbr>New();<br>
foregroundRenderer-><wbr>InteractiveOff();<br>
foregroundRenderer->SetLayer(<wbr>1);<br>
...<br>
GetRenderWindow()-><wbr>SetNumberOfLayers(2);<br>
<br>
Hope that helps, it's the last idea I have :p<u></u><u></u></p>
