This one is really a bonus! Earlier, I got to upload another video about doing caustics in Blender Render for an anime style, which you can watch here. This video came as a result of having to learn that, like I mentioned in the video.
I just want to caution you to always time your animations. Even though you may think that they look right, if you don't have the fastest PC, odds are you need to do some sort of test before final render to make sure everything is at the right speed. Learned that the hard way with this specific video! Learn from my mistakes! haha :D!
