Disable shadows?

My situation should be simple. I’ve got an object (a skybox) that should NOT cast shadows.

I’ve set my lights to Sun lights, RayShadow on, and set “Traceable” on the skybox to off, but it’s still blocking the lights. Is there another way to tell an object not to obstruct my lights?

Edit: Disregard this. It looks like another object was responsible for blocking the light! I had a second skybox that was still traceable. Looks like it works exactly how i thought it should.

move the sun inside the sky box, this doesn’t affect the brightness or orientation of the sun.
