Digging around in the included examples with C2, I came across the lighting.capx file that (apparently) was created by ASHLEY. (LOVING the effect, too! I'm gonna use it somehow.)
The effects and settings for the image sprite seem straight forward enough. But when I examine the animations part, I'm not quite sure if that's truly an imported image or what... Ultimately, what I'm seeking is how to initially START the object. Is it just a dot that's manipulated further? An imported image? What?
