Dear readers,
I am very anoyed at my self coz i have no idea as how to create the harry potter spell thing. I saw the hitfilm tutorial but I need to make one that looks a bit more like the video thing from the thing and the deathly thingys part 2. The steamy things need to be flowing towards the middle somehow i think i should use a partical sim but i dont have a clue how to use that thing!!!
