[vtkusers] vtkLightKit and OffScreenRendering

[Paul Tait - OPES]

Hi
 
I can confirm that this happens but no one knows why!!!! I asked the group
about this over a year ago and the only suggestion was to turn the
vtkLightKit off before rendering off screen to force the use of the standard
lights. Let me know how you go

hi,

I'm using the vtkLightKit class to adjust the lighting of my scene. 

When I switch to OffScreenRendering and use then vtkBMPWriter to get a
screenshot,
the colors of the image are dimmed, as thought there was no lighting
present. 

 I also tried to use the 
dynamic_cast<vtkWin32OpenGLRenderWindow
*>(renWin)->SetupMemoryRendering(size[0], size[1], GetDC(p_hwnd));
capability of the OPENGL32Window directly, with the same poor results. 

Any ideas?

VTK 5.1 (CVS updated on 10.01.06)
VS 2003
CMake 2.2 1-beta

thank you in advance,

yianis
