spring bone ?

[createo]

Hello,
I am looking for a video illustrating a basic explanation on the spring bone system: the procedure of installation and use?
thanks in advance

Would you believe I've never tried that?

Those were introduced as part of an early "cloth" simulation technique. There was also a wizard you used to set up a whole bunch of springs over a mesh to make it behave like cloth.

But it was soon replaced with the SimCloth we have now which is much more useful.

I just tried making a simple Bone to Spring constraint and I think something is broken about it. I can't select the target "spring".

I'll try to make a bug report to Steffen.

If anyone knows more, I'd be eager to hear it.

Following thread, I am interested in knowing of the bone to spring and spring system. This would be a good saturday topic @robcat2075.

Hello,
I just watched "Alien Song" which it seems was made with Animation Master.

Isn't the flexible "antenna" on the alien's head made with a spring bones ?

Greats

I'm pretty sure Victor Navonne animated that manually.

It's possible we had dynamic constraints in A:M back then but I don't think he used them for that project.

BTW, when you asked about "Spring bone" I guessed you meant the constraint that is actually called "spring"

If you mean dynamic constraints that work kind of like that antenna in "Alien Song" those do work properly in A:M.

Is that what you meant or did you mean actual "spring"

yes, I wanted to talk about the dynamic constraints which work a bit like this antenna in "Alien Song".
What is the basic procedure for these to work properly in A: M ?

Thanks

Here is a simple case you can try

download this PRJ...

Dynamic Demo001.prj

In the Chor a simple alien head is animated to wag back and forth.

on Objects>Alien Head... >New>Pose>On-Off

In the Pose window the antenna has three bones. One the last one >New Constraint>Dynamic Constraint

In the properties for that new constraint make the following settings...

 

In the properties for the model turn the Pose ON...

 

 

Play the Chor. The antenna should bend and wave.

Experiment with lower "Stiffness" settings

Experiment with higher "Drag" settings

excellent !!
This is exactly what I was looking for and I didn't think of putting this property in a pose!
Thank you

You can do this constraint in the Chor but for a use like an antenna on a character you probably want to have it ready every time you use the character so doing it in a Pose is better.

The Hash Tech Talk for Dynamic Constraints (and many others) can be downloaded from...

The ones that are MOV format can be played in VLC media player

Some of the presentations are in the old SWF format. Playing details on Tech Talk page.

yes !!

thanks
