Hi,

I am currently trying to make an animation for a man walking up stairs. I have created the animation (using bones) in MED and while running it through the cycle in MED it looks perfectly fine. However when i watch the animation in the game there are odd deformations that occur. For example when he lifts his leg up the calf and everything below it shrinks. And the longer the distance the more deformation (shrinking) occurs. I thought that perhaps i just didn't have enough frames so i added more frames but this creates a kind of bobbing effect and there is still some deformation. I went through all my animations and apparently they all do it i just had not noticed it up until now because the other animation movements were small. I'm not sure if this is an engine problem and i haven't been able to find much info on the forums.

I am using LiteC 1.70.1 and the MED that comes with it.

Thanks,
AJ

Hi,

did you try your animation code with a different model? Just to be sure it happens not only with your model. Next would be to check if the animation looks different with different code.

We had some problem with interpolation some years ago, but this was only visible during slow motion animations.

The only code that i am using is the ent_animate to be specific the exact code i am using is:

my.skill20+=1*time_step;
my.skill20%=100;
ent_animate(my,"Leg_STAIR_UP",my.skill20,ANM_CYCLE);

i have created a seperate fresh script that had nothing but the entity and the animation code and still have the same problem. I have also tested with different models as well as tested by converting the model to points animation and the results are still the same.

Thanks,

Hmm, not sure but try this instead.

my.skill20+=1*time_step;
ent_animate(my,"Leg_STAIR_UP",cycle(my.skill20,0,100),ANM_CYCLE);

And let us know how it goes. If it make ANY difference...

thanks for the reply

unfortunantly there is still no change. Its almost as if the bone itself is resizing during the animation.

the odd thing of it is that the animation works perfect in MED but not in the engine.
also if i manually rotate the bone through script using ent_bonerate there is no problem.

Try creating (in your fresh script) keystrokes to change ent.skill20 manually
and have its value displayed as a number in a text panel or something.
That way you can see if any odd numbers are getting into skill20, or at least
exactly what values are making it go screwy.

still the same nothing unusual in the skill20.



maybe this will help

as you can see the left leg which is being lifted starts to deform from the knee joint down shrinking the calf and foot

Looks like it is doing a ent_bonescale to the lower leg and beyond.
When you were displaying the skill20, what are the values it seems to
be freaky between (2 decimal places if possible).

Also, try creating a duplicate model and convert it to vertex animation.
See if it still does the same thing.

Its starting to look like a bug in the engine interpolation, whereas MEDs version is OK

i tried swithing to vertex animation and it still looks the same. I will get the values from skill20 for you this afternoon. Thanks for your help EvilSOB

Thanks,

No problem, also, any chance of you posting (a link to) the model?
(dont need textures it its big, bone-anim by preference...)
PS Is it just one leg or both? (if just one, which one?
Looks like his left in the pic.
