>"Make light not touch stuff... I'd actually been wondering about how an object could cast no shadows. I mean, the tree still looks solid, and feels solid, so why doesn't it seem to block the light like normal trees do? If you know how to make light not touch things, do you have any idea if this could be something similar?"
