Hi Junhwan,
One more confirm. Is the "t" in ray["t"] the built-in field (like Density) or the derived field that I need to make in my own?
To be pedantic, "t" is a derived field, but it's already defined for you for ray objects, so you can just use it. -- Stephen Skory s@skory.us http://stephenskory.com/ 510.621.3687 (google voice)
