How To Make A Stretchable BoneChain In 3DS MAX

[@henriqvist]

@teetime91 you try this: create a shape to be parent of the main bone, so when you create the IK, you link the last shape to this main shape and not to the bone. and the middle shape should also be child of this new shape. also, pay attention who is the parent of the Expose Transform, because Max have some refresh issues

[@Mummy542]

you are genius!! It's just wat I need all this years))

[@reecpj]

That is fantastic. I've wanted to be able to do that for ages, thanks a lot!

[@henriqvist]

yes, thats the idea. but the way I do arms and legs actually is a little bit more complex, to have the twists and bendy modes...

[@Dephunkt01]

This is amazing, thank you very much; so much less hassle than scripting it!

[@lordcolombo]

Very nice man, I wonder how you discover this sequence of linking the chain, control objects, iks. Thank you very much!

Thank you so much for sharing this! Truly a lifesaver. Also subscribed!

[@alzarac3d]

Excellent!!! easy, faster and usefull!!! Thanks for sharing

[@Jimbojones060]

Fantastic tutorial! Could this be used on a fully boned IK rig, for stretchy arms/legs? Thanks

[@craniummatter]

thanks! and nice soundtrack choice.

[@mesquita3ds]

Ótimo tutorial, contribui muito para o que parece complicado ser simples. Grande contribuição :) Valeu!!!

[@teetime91]

Great stuff here!=) But i get an error when i use this method, when i Wire them together. It say's: There is an illegal self reference involving the Ik chain node in the exposeTransform expose transform helper. in order to fix this the exposetransform expose node will be set empty. Where did i go wrong? I use max 2012.

[@dilithium72]

Seems to work fine in isolation, but as soon as you try and combine two solutions to a pelvis (Bone/Dummy/whatever), it complains about the illegal self-referencing.

[@henriqvist]

yep, you have to be care of who's gonna be the parent of the chain

[@dilithium72]

henriqvist I ended up with a couple of position constraints to some dummies/hips.

[@alianjaro3089]

Hi, If I created only one bone and an end bone and did the same as you did, would I be able to shrink the bone (as in "stretch" it to make is shorter)?

[@henriqvist]

Alianjaro yes, put a shape son of the main bone, just as the end bone, then do the IK between that shape and the main bone, than pick the solver and put a position constraint to the end bone... no sorry, pick the end bone and put a pos constraint to the IK solver

[@alianjaro3089]

henriqvist Ahh thanks a lot man, sorry for the late reply. You helped me a lot!

[@gasparenigam]

Hello,how to reduce stretch weight (stretchable)?

[@henriqvist]

Gaspare nigam you wold have to think of a way to short the distance between the nodes, maybe a pos constraint and control its weight..

[@JozefKonradPlata]

I dont understand this postiion constrain to IK, I cannon make that link: Cannot link: would create dependency loop :/

[@remithivierge8528]

is this method follows into Unity?

[@henriqvist]

no, for Unity you need to use another bone, set him child of this bone, and convert his scale to follow his parent strech using Scale Script

[@remithivierge8528]

Thanx fort the quick answer.

[@henriqvist]

try running this script with this new bone selected: $.boneEnable = off $.scale.controller = scale_script () $[3][3].addnode "me" $ $[3][3].controller.script = "if me.parent != undefined then (me.parent.stretchTM.scale)else([1,1,1])"

[@remithivierge8528]

henriqvist Ok, I'll try that. You just save me a lot of time! I'll tell if it works for my rigg.

[@remithivierge8528]

Rémi Thivierge and..... it works. thanks a lot.

[@LokiLegioner]

I don't understand how it works! Will it works if we have tree bones or more?

[@polygonmonkey]

more information in3 minutes, than is some 1 hour video

[@BeNj0000000]

Smart but i had a hard time when i wanted to link all the system to a global dummy or my foot controller.I fixed after a long time....but thank you very much

[@EugenicaMusic]

Impressive, but non-informative. Useless.

[@fernando749845]

No, YOU are useless if you don't understand its purpose.
