Hi, Mr!  
I notice that you had given some useful advice in the post([How to only render one vtkRender in vtkRenderWindow with two vtkRenders - #8 by Pisces2018](https://discourse.vtk.org/t/how-to-only-render-one-vtkrender-in-vtkrenderwindow-with-two-vtkrenders/11425/8)) Could you please give me some help about this problem?  
Great thanks!
