I was wondering what to do for the transitions in and out of rooms in Mirama, and I did not want to make sprite animations for it -- the effect I wanted to go for was an Iris Wipe, and for it to be centered on the player, each frame would have had to be 4x the screen resolution to account for corners.
So instead I came up with this little... 3D Tube that morphs into a cone!
Being new to making games and all, maybe this is a trick people have figured out before (or one that sucks 
), but I felt pretty good about coming up with this solution!
