How to light object from inside?

I’ve been trying many combinations of lights, halfway-transparent materials and Render Transparency settings, and I haven’t yet properly wrapped my brain around the methods for getting ‘realistic’ alpha blending in TD.

I want to simulate lighting up objects - spheres, to start - from the inside. I can place a light inside a sphere and see it light up if my camera is inside as well, but I want to see it lit from the outside. Has anyone done this?

Aha! One key setting seems to be setting the material for the target object to have its Front Faces Back-Lit (frontfacelit:backlit). This makes sense.

Ha! Thanks for working that out. That’s on my list of things to try.
