With lights disabled, how to draw coloured 3D lines?

[mant]

Hi Everyone. I'm doing a simulation application and having a little problem. As I use:

smgr->drawAll();
driver->draw3DLine(lineStart, lineEnd, video::SColor(0, 255, 0, 0));

The 3D lines are always black. Can someone tell me how can I change it's color without adding a light scene node?

try setting a transformation matrix for the video driver and try SColor(255,255,0,0), so that you have alpha
