Using PoseRay you can reder the scene with POV-Ray (www.povray.org). POV-Ray is a free high-quality raytracer. In PoseRay you can chage the transparency of the umbrella material and the light will shine through when you render the scene in POV-Ray.

Check PoseRay's manual for a simple tutorial.

good luck,
