Hi all,
here's an animation test I did with the Andy Rig.

Think it would benefit from an upper torso move back with the remote extended towards the tv and a freaked out facial expression when he says "its freakin me out" maybe a quick head nod horizontally. Needs a strong end pose. Nice work though.

Hi all
Thanks ColdWave, I'm sure there's alot I can improve
Hi Ocinneide, you're right about the pose on 'freaking'. I think that would def help. (Andy rig is alittle unflexible when it comes to facial expressions tho..) Heh, anyway youtube ate my last 15 or so frames from that clip.

Here's another assignment I imposed on myself..
Walk cycle, WITHOUT cleanups or polish. Just wanted to try and capture the broad motion and feeling.

I re-did a walk cycle, just trying out different ideas and methods.
again, not polished off, just trying to capture the broad motion.

The problem I see with that is that the main body jerks forward while the trailing leg is off the ground and passing forward also, which is the time when he is least able to apply any force to make him go forward that suddenly.

In general, in walks the forward progress of the main body tends to be pretty steady since it's the largest mass.

Hi robcat2075
thanks for yr comments, I really found it useful (i dunno why i din't realise it!)

I've done another walk cycle, so maybe this one is abit better.
again, not as polished, but just for the broad idea.

There's some sort of a jolt happening in there that looks odd. But hard to diagnose since Youtube wont' let you scrub by frame.

Hi all,
hi robcat2075, I think the jolt you mention is when he moves his head upwards? His left arm seems to swing up at the same time and therefore think it gives the sudden 'jolt'.

I've tried to smoothen it alittle, and the arms as well.

let me know what you think!

without being able to scrub it, these are just guesses...

-the overlapping up-down motion on his head isn't timed right

-serious knee pops on the left leg

-his hips don't really rotate. They move up and down a bit, but appear frozen in all other regards. Hip rotation is quite complex because it is doing something different on each axis. Describing it is beyond text message here I'm afraid.

Hi Robcat2075
thanks again for yr comments, they really do help..
I've tried another walk taking into consideration the hip movement. Toned down the arm swings and body swings and cleaned up the pops slightly. (There are still pops but not as big i hope!)

Sorry, I'm not able to host a .mov file (for scrubbing) but you can get the wmv here

That's a plausible "attitude" walk. It's not "generic". It's more like she's walking across the room to punch some kid out.

it seems a bit fast and tight, but for that attitude... why not?

Ya know... I wonder if that would get better if you just stretched it out to about 1/2 second per step?

Hi all
hi robcat2075, my prev walk was done in 25 frames/cycle, I realised early on that it made the walk feel abit fast. Just to let you know, it wasnt meant to look like an attitude walk.. my bad!

I tried another walk on 33 frames/cycle and I think its slightly more relaxed.
here you go, vanilla walk. I'm aware of slight poping in both knees (I hate these.. any strategy to minimise or get rid of these?)

slower is better on that one. I'm beginning to think a good rule is that the shorter the step, the longer it should take. I think that's generally true.



here you go, vanilla walk. Something is still odd and not flowing right, but it's beyond my ability to diagnose without scrubbing it frame by frame.

I made some videos on the mechanics of walks for some people I was coaching, they're not complete coverage of walks but you may find them useful.

scroll down to "Walks (http://www.brilliantisland.com/am/amtutorials.htm)"





I'm aware of slight poping in both knees (I hate these.. any strategy to minimise or get rid of these?) One trick is to slightly scale the legs shorter or longer to fine tune the position of the knee. If your rig doesn't do that then you'll have to fiddle with the heel raiser.

You do either of those on a frame by frame basis after you have everything else squared away.

I worked on a very modest movie called "The Tin Woodman of Oz" and they invented a rig that could seamlessly switch between IK and FK on a leg or arm on any frame. With that you could pose the leg in FK while it was in the air and that pretty much solved the knee pop problem since the knee was being animated directly.

The shoulders and the hips dont sway at all in the casual walk. The sway of the hips creates efficiency in the walk, and the shoulders sway opposite to maintain balance.

Clearly you can see in the front view: the hips tilt only very slightly and the shoulders not at all.

Also, I think the popping might have been caused by having the back foot leave the ground too late. It's causing a timing issue where the foot seems to move too fast for a relaxed walk cycle; it seems like it's trying to catch up.

Hi all,
hi robcat2075

here's yet another walk.. I went thru yr tutorials for walks. Found the leg positioning quite useful. That was prolly one of my bigger mistakes.
i hope you do more tuts like tat, they are really useful!

dbalmert yr rite. The chest rotation and hip sways were missing from my previous walks.

Is this better? I hope so!
Also, pls ignore the 'wobbly legs' i dint have time to clean those out

Looking a lot better; fix the popping and it might be finished. I'd have to see a final without the popping though. It's kinda distracting as is.

Hi all,
i've decided to start with doing runs..
here's my 1st go at it. Isn't that great tho, I've prolly get another one out soon

NooooOOOOOOooo!

He's supposed to lean forward! A run cycle is supposed to be off balance. The character should appear in balance only a few frames out of a run cycle.

Yours has a stick up his butt all the way to his neck.

He needs to swing his arms a little more. the weight of the arms and hands add to the forward motion and help your body fall directly forward instead of diagonally forward (because you're on one foot.)

Your hips need more twist (from the front view) each step. When running, your body tries to plant it's feet close to the center axis of the body to maintain balance. That's why some people trip when running - their feet collide on the center axis.

This guy's feet never make any motion toward the center axis.

Another subtle thing is the ball or toe of the back foot twists slightly before leaving the ground. It's another efficiency thing.

Yeah, that does look better. It still seem stiff. maybe because the spine so straight all the time.

The run is not a bad start, but I agree he should be leaning into it.

I think runners tend to carry their arms higher up rather than letting them hang as when they are walking.
