### My Question

Hi,

I hope it is just a simply issue:
I have imported a .ply file with quite a big surface and added point light to render.

While I'm moving the camera higher the light is cut, or camera has something like a far light cut? Anyone knows how to solve/change that
...

` render.scene.scene.add_point_light("swiatlo", [100, 0.5, 50.0],[566591.49, 241480.53, 205.09],10e8,10e2,True)
render.scene.scene.enable_light_shadow("swiatlo", True)
render.scene.scene.enable_indirect_light(False)
render.setup_camera(50.0, [566591.49, 241480.53, 203.09], [566591.49, 241480.53, 310.09], [0, 0, 1])
img = render.render_to_image()
print("Saving image at test2.png")
o3d.io.write_image("test2.png", img, 9)`

?

Thanks for any help.
