Kernon has been steadily creating new videotutorials. And even though he's a writer here at BlenderNation, he's either too shy or too modest (I'm voting for the latter one) to publish about any of them! Anyway, here's his latest tutorial: creating glint effects in Blender with Halo effects. The method allows for exact placement of glints in your images.
Adding glints to your scenes can add an extra touch of realism and excitement. This video tutorial will show you, step-by-step, how to easily add glint effects.
Basic Compositing using the AlphaOver node
Even though the method doesn't work well for animations (well, it works, but it's a LOT of work), I think it's a great way to have exact control over the placement of glints in stills.
The tutorial is half an hour long, and you can either watch it online or download it from Kernon's site. Enjoy!
