For months, I have been pondering on the technique used to create the shiny beveled edges found in several official Megaman logos. For a while my guesses skewed to pixel-based bevel effects in Photoshop. Finally, I've realized how this effect was done, in vector. It's a little time-consuming, but fun.
Here is an exaggerated example done in Inkscape.
It can actually be done in Adobe Illustrator along with Inkscape. I just downloaded Illustrator, but I accidentally got CS3 which is clunky and illogical compared to CS4. Both programs have their advantage when doing this. In Inkscape and Illustrator, CS4 in particular, the gradient can be moved around freely. In Illustrator, blending modes can be used as opposed to Inkscape which only supports blending modes in layers. A blending mode will make the effect shinier and applicable to any background. However, Illustrator isn't so great at clipping. At least I haven't had an easy time applying some. Plus, it doesn't support gradient strokes, but that can be solved easily. Inkscape can generate the line segments faster than Illustrator as far as I know. I'll gladly write a tutorial on this soon since it has bugged me for so long. Then maybe the technique can be improved upon.
