OSL, short for Object Source Lighting, is a technique that's not easy to get right.
The simplest way to achieve it is with an airbrush, first applying white to the source and then glazing a desired light colour over it, but for a really convincing effect, more steps are required.
We simplify these steps, teaching them in our OSL tutorial over at the Grimdark Compendium. We'd be glad if you consider checking it out!
