About two months ago we reported on a contest to create the most realistic explosion in Blender (Elysiun thread here). There were many fine entries, but this one by Rhysy2 was the clear winner. Great job to Rhysy and everyone else that participated!
Not content to sit on the knowledge himself, Rhysy has been kind enough to create a tutorial for everyone to download (.pdf). Don't forget to let us know what cool explosions you come up with using this technique. Now if Rhysy could just write a tutorial on how to pronounce his nickname.
Update: this tutorial is now also available in German.Â
