This is a great tutorial by Ron on creating a good glowing powerfist. It’s where I got my start down the road of OSL. While the tutorial may be old, the theory and concepts remain current, so it’s a great place to start learning about OSL if you’re new to it.
So I offered my opinion on the model when Matt posted it on his blog. And after offering my two cents, I thought about it and figured I should at least offer my solution to creating the glowing effect. I don’t think the process is too terribly difficult to recreate, but I will say this:
1. It’s not a quick process.
2. You need to be comfortable painting fine details and blending.
3. It requires a basic knowledge of object source lighting.
