abvfx Posted December 19, 2008 Share Posted December 19, 2008 Quick question guys. I was wondering because i know it will help me out to have real Spline IK. A combination of Spline control and IK control. I don't mean "Follow Curve" because that does exactly as the name describes. I mean something like follow curve with an IK handle at the end so i can move the goal which will bend the curve and then i can adjust the actual curve, with persistent handles or whatever control i want. It sounds like im going to have to build something that will generate this effect but i know it would be extremely useful. If im not mistaken this is how the spline IK works in Maya. All thoughts are welcomed. thank you for listening and helping out. -andrew Quote Link to comment Share on other sites More sharing options...
abvfx Posted December 20, 2008 Author Share Posted December 20, 2008 something like this. But im no rigger and it has way to many problems to make it easy to animate. Just use the anim ctrl to get the idea. The visibility is turned off on one anim ctrl. This determines the slack of the spline IK (sorry dont know the right terms here). Someone must have a better solution. oh and sorry about the crappy stretch and scale of the scene. I kinda threw this together as quick as possible. splineIK_hack.hipnc Quote Link to comment Share on other sites More sharing options...
Richard Posted December 20, 2008 Share Posted December 20, 2008 not sure if you have seen dont know much about rigging myself but I think you looking for a strecthy spine ik and chris talks about something similar on this thread. Hope this helps Quote Link to comment Share on other sites More sharing options...

abvfx Posted December 21, 2008 Author Share Posted December 21, 2008 Cheers Richard, I have seen that thread. But in the spine post its more Stretchy Follow Curve. If people open the file and try it you will see it is more like Spline IK. Moving the targets create a curved shape and rotating them works well in adjusting them, but if you look deeper you will see whats going on. I may have to create a quick demo if people don't look at the file (only 2 people ) -andrew Quote Link to comment Share on other sites More sharing options...

abvfx Posted January 10, 2009 Author Share Posted January 10, 2009 Have a little play with this. I found some help on the SESI forums and even though i figured it out eventually by myself, it was pretty much a fluke and i got the proper reason why things didn't work out. This file has pretty much everything working accept twisting. So play, animate, stretch, squash (although i didnt enable it to scale in laterally since it looked weird ) and tell me what you think. (i think i need to build in a shader/sop work flow when the model is stretched, because its way easier to go off model with this setup, ut it does allow more freedom) Enjoy. -andrew (and i will probably do a video demo, if its really needed, if not how to use it then how to put it together) FollowCurve_Working.hipnc Quote Link to comment Share on other sites More sharing options...
