Poser - OFFICIAL F.A.Q (Last Updated: 2024 Nov 21 6:06 am)



Subject: Newbie question about sliding feet in Poser


poolofice ( ) posted Sat, 17 April 2010 at 10:16 PM · edited Fri, 22 November 2024 at 1:18 AM

This issue has probably been dealt with earlier in the forum but nevertheless...

I have Poser Pro. My problem is that when I animate a character from one pose to another the feet aren't glued to the floor. They slide. So, as the movements are made it is as if another bodypart is fixed in space while the feet are not. It's like a skating effect.

I choose one pose, jump 30 frames ahead and put another pose there. It would look beautiful if the feet were anchored.

I'm sure some of you had the same hurdle as beginners.

I dont understand animation but do you have inverse kinetics ticked for both legs? ... (i'm just throwing this out there)

You gave the answer yourself:

Quote - it is as if another bodypart is fixed in space

For most static poses, the Body actor remains fixed in space (although a Pose can translate it).

When you apply a Pose, the Hip may be translated (moved) and rotated with respect to the Body. The Thighs may be rotated with respect to the Hip, the Shins with respect to the Thighs, and the Feet with respect to the Shins.

This is why the feet will end up in different positions in 3D space, and an animation between the poses will slide them between these two positions.

Oops, a minor omission.... a figure's Body actor can also be rotated, not just translated.

Turning on IK for the feet will lock them in place but might not give you the pose you were expecting.

Thanks a bunch. Not far from solving this mystery grin. I understand what you're saying, just have to adapt it to practical knowledge. You know, step-by-step procedures and what-have-ya.

Thankiez again

I think you just hit the nail on the head there. If my memory serves me right they were both ticked, but I'll double-check it. : )

The reason why I am more interested in animation than artwork is that I suck at the latter... I'd rather do a half-ass ( = half-donkey mind you) animation than fail completely at artwork.


markschum ( ) posted Sun, 18 April 2010 at 6:45 PM

no one fails completeley at artwork. You can always claim it supposed to be like that, its ART and you just not understood by the philistines :) 

by all means try animation, its not as hard as many people believe.

Hi Pool of Ice

If you figure it out- please post the solution. I never found it myself. I considered rendering the animations on a virtual Ice Rink-so it would look natural! :-)

I have a hard time with this as well.  I usually scrub through the animation and try to lift the feet on the between frames, but that is not always successful.

I had this and the only solution I found was to put in extra key frames. Plenty of em! :D

If doing it manually, a few extra keyframes and careful use of spline break, or one of the other interpolation modes may be a good idea. Watch people just standing around waiting. They change position and feet do move. You can put that in an animation by lifting the foot just a fraction between poses.

The basic problem you're running into is this. Most canned Poser animation poses do NOT affect the body's position. You then have to manually translate the body position by hand. A really good animated pose will move the body as well as the extremities. Once you just start learning to animate the figure by hand moving the body along it's transit axis, you'll get rid of the slidey feet problem.

IK on the feet will NOT solve the problem! It keeps them locked in place with the hip. Breaking the IK chain and attaching the feet to the floor just adds headaches to the animation process.


shedofjoy ( ) posted Mon, 19 April 2010 at 2:18 PM

I have not tried this but what about turning ik off and parenting the feet to two seperate objects below the feet, then moving the objects around in the X and Z axis so that the feet are fixed to that location....or perhaps a figure that consists of feet that another characters feet can be parented to??? hmmm just ideas

Getting old and still making "art" without soiling myself, now that's success.

did ockham have a "sliding feet" script?  i feel uncomfortable with most of this thread.
IMVHO if it's worth doing well, use bvh files.  if not, just do it manually and slap a keyframe in,
every 15 or 30 frames.

Hi while I certainly agree with your advice about learning to animate by hand
you could NOT be  MORE WRONG in the above quoted portion of your statement

The O.P. is Obviously a beginner at poser animation.
 He/She Has three  options:

Scour the web for Canned BVH File/ animated pose sets& scripts and hope for the best "fit" as far as results with the figure in use.

LEARN how to use the tools in poser ( GRAPH EDITOR,DOPE SHEET &IK)
and create there own original character animation.

( RECOMMENDED!!)

Use the FREE version of Daz studio & BUY the "animate+ plugin for it and do ** THIS**.

You have NOT pointed out how breaking the IK chain and linking the feet to the floor or other objects gives less headaches Wolf. I don't mind if you disagree, but show me why please. And as this is the POSER forum, I expect the answer to be "For Poser" and not DS! Kthxbye! 

Someone else mentioned breaking the IK and linking the feet to two separate objects. Again, I have to ask WHY? You can move the feet just as easily and acheive more natural results leaving IK intact and manually animating the feet yourself. Breaking IK in hands and feet is the long way around in my opinion and unless you can show me how it's shorter and less headache inducing, I'm standing by my experience in the matter.

Hi I obviously Misread your post ...apologies
I though you meant IK in general "adds headaches" to animating.
you and I are actually in  complete agreement here.

as the link to my video tutorial in my first post in the thread
indicates  about the importance of IK
what the other person was suggesting about"parenting the feet to props" is completely counter productive

it was steve who wrote the "no-skating" script (see att. lnk).  I reckon it's a challenge doing these animations manually, but one might be surprised to find that the pros don't do it that way.  poser is ridiculed by users of higher-end apps because its user galleries are full of nostril-glow nudie pix, but what would they think at CGtalk if they found out poser users were resistant to bvh as well?

No worries. I loved your tutorial and it made me wonder why you disagreed with me. :tt2:

I probably could have worded it better by saying "Breaking IK on the feet will NOT solve the problem!" I did clarify, but I could have made it clear to begin with. I need some caffiene.
