Hello,
I’ve a problem with the Light Comp in my network, when I change the light color, it doesn’t take effect on the render top :
the lines are still in white color and dark, even if I pushed the dimmer to 1000 
Do I miss somethings ? 
thanks in advance 
Hi I am assuming that you are using a Line MAT to render this. The Line MAT by its nature is not affected by the Light COMP. The shading you see is affected by the distance to the camera for each point. Try adjusting that in Line MAT to color your scene.
Hi, yes I’ve a Line MAT, so I change colors directly from the MAT.
thank you
