Sorry for the delay on getting part two out folks. Life ya' know! Posted Image

For exercise #2 we are going to look at simple gravity and how a fall influences the shape of our flour sack.
You need to begin your scene with your flour sack sitting on a table or counter top as illustrated in the below depiction. Your sack should fall forward onto the surface of the table (counter, whatever..) and then off and onto the floor.

Posted Image

Some considerations for you:

Technical Wise
1) Start this very first animation at the NTSC standard frame rate of 30 fps. While this isnt mandatory, it is a good habit to get into early.
2) Animate on "twos". This means that every second frame of your animation is a repeat of the frame before it. So even though you are animation at 30 frames per second, you are actually only drawing out half that amount.
3)While it is possible to do this exercise using motion tweens and the line tool, I would suggest drawing each frame individually and getting the full idea of what is involved in fxf animation.

Character Wise
Try to really bring life to your sack falling. Look for good reference on the net, or create your own. Study how the weight shifts within the bag itself as it starts to move, and then recreate the effect. The background (i.e. The table) doesnt have to be fancy, and dont really concern yourself with a high level of detail or much shading.
We are trying to keep things simple for now. The important thing is trying to capture and depict the movement of the sack. This is one of the exercises that can really wrack your nerves, and is known as a toughie. Dont rush yourselves, and dont get discouraged! Feel free to post up your WIP's and get feedback as always!

We will get to part #3 where we will get our 'lil sack up and moving all on his own when we get some finished works on this one!
Enjoy! Posted Image

Maybe slow down the pause before the second part of the fall, or make the weight slowly shift forwards, that pause doesn't look natural :)
Other than that, great work :)

The toughest part for me is the landing, making the sack come to a completely stopped position without it looking to much like a sack full of water when landing.

My Sack!!

Second part is too slow, maybe try to make it land on it's side?

com, yours looks pretty good. One thing you might wanna add though; when the top of the sack tips over and the sack stays stil for a while, try making the bag lean forward alittle bit more each frame before it falls. If the bag just stopped there would be no reason for it to fall off.

The fall is a bit choppy. You could try to adjust the spacing between each frame.
Make it accelerate a bit more for each frame:

heres my with onionskin on. You must have a smooth acceleration starting from the top to the bottom of the fall. Mine isnt that perfect either, but I hope you'll see what I mean

:bfoot:

Update 2
(hit refresh if the "update1" animation shows)

Heh nicely done :) I think the second looks more like its filled with sand due to the top of it crumbling in a bit... personnal opinion :)
What about making a bullet time version? :P

Dude, I dunno.
But mine's doing the same :worry:
It's like a fraction slower, just enough to be frustrating. WTF?

jabronimon, songspinner:

You must increase the frame, when youre gonna export it as SWF.
forexample, Adam Phillips have 30fps. But he increase the framerate to 31 or 30.7 or whatever.

So just increase your framerate with a couple of decimals. That should do the trick

Thanks comlock, still it runs a little weird but it's better, anyway i just now noticed I did the exercise wrong, i have brought mine to life and made it jump by itself instead of just letting it drop of a desk or something, anyway here's mine:

Interesting, but maybe not enough motion, chances are a bag would topply over, and the sand would shift weight :)

Spinner maybe you should show the wieght shift a bit more.

Here is my attempt, I really wanted to add a life to this sack thingy.

The double fold at the end looks a little unreal, maybe the top should just flop over the bottom instead of a double fold... flop over with a crease in it or something... just an ppinion though, consider it or discard it.

Yeaa, I guess unless there was a bunch of flour in the top of the sack it wouldn't really squish like I have it. Thanks

There is some great work going on in here thus far.... but just a note for ya'all... dont get carried away with too much detail (again), and do not try and personify your sack yet. We will get there I promise, but for now it is important that you concentrate on trying to capture the essence of "shifting weight". That should be your sole priority for this exercise. Posted Image

I got yer back bud! Posted Image

Right off the bat... too much personification happening KiWi. I know you are one of the ones just itching for this damn sack to sprout legs and arms... and he will... just be patient! Posted Image
Go back and just work on capturing the movements that would occur if the weight of the flower "shifted" causing the sack to flop over onto its front, then over the table. The fluidity of the motion is key to this exercise, so dont add any effects, just work with weight transfer.
As well, your sack "flaps" should be very loose at this stage. Think about how the shift in gravity would affect the flaps especially, being as they are not directly affected by the shift in weight as much as the motion of the entire sack.

I hope you redo it man, I'd like to see your results!

Hokay... ta Kiwi.
I added some more frames at the beginning for the weight shift, and took out part of the landing at the end, because it looked more filled with thick rubber or old jelly instead of flour.

Attempt v1.4
If you've watched it before, be sure to refresh your browser so you get the updated version :\
