Making glowing lines and shapes

Questions & Answers
1

I’m working on a game right now where the player is assembling magic symbols and runes. To fit the theme, we’d like these runes to glow at certain times, however I’m having a hard time figuring out how to do it.

I’ve seen it suggested that you can add a glow effect to the camera, and then adjust the individual alpha values of different objects; however, since the objects are 2D, adjusting the alpha channel just makes them invisible.

Does anyone have any other suggestions for ways to achieve this?

So my solution was as follows:

Create two versions of the shape in Photoshop, one with an outer glow and one without it. Put the non-glowing one directly on top of the glowing one, and then assign them to their own layers with their own light source. Then you can adjust the brightness and opacity of the glow separate from the object itself.
