Hi !
I’ve been using this plugin for a long time now, very useful !!
But i’m still trying to disable the stretchy effect with a slider whenever i don’t need it.
Anybody managed to do that ?

Thanks

I hope somebody still checks this thread from time to time. this looks really cool but Ive managed to screw up the installation somehow; when I install the plug-in (and after that if I try to look at its properties or anything) I get an error saying it causes conflict with a plug-in with the same name and of the same type. which sounds like Im trying to install it twice or two different versions. but there is only the one, its the only one showing up in the plug-in manager. I tried deleting it and doing it over but it doesnt help. every time I install it I get this message. anyone had a similar experience and how do you fix it??
I’m using 6.5.
thanks for all your good work andy! cheers /matt

Hi guys. Don’t know if you solved your various problems but from now on could you send any inquiries to me directly via http://www.andynicholas.com. I don’t seem to get any alerts to new posts here.

Thanks :-)

hy andy, thanx a lot. this is really an amazing tool.
we (http://www.xsibase.com/forum/index.php?board=11;action=display;threadid=34367;start=0#lastPost) have been trying to compensate the scaling by a Global_SRT, in other to have it working on a scalable rig. from a first glance i believe the “boneScale” should be divided by (1 / Global_SRT.(scale)Value ), but i am not being able to access it from the scoop. does it seem like a right way to go? any other ideas?
thanx again!

Oh, weird, if you put both the ’soft effector’ and the ’stretchy soft effector’ on the same bone chain you can blend from one to the other by adjusting the blend wieght on the end effecters position constraint. The only issue (which is a slightly large one) is that the bone length is still adjusted bu the ’soft stretchy’ effectors distance from the root.
hmm, getting closer though. maybe?

Hi there Andy, I have just been checking out your soft ik stuff and it is great :) thankyou!

I was just wondering though, if you had looked at Erics issue at all? It would be great if you could ad a slider that stopped the stretchy bone from being stretchy, I don’t know if that would be way too much of a mission but it’s something I think is pretty handy in a stretchy rig.

Fantastic - solved all my “pop” problems in a horse rig I made - I retrofitted it to all the rigs I currently use.

Thank you!

Oh, and don’t forget to plot the bone length parameters too!

Sorry, I replied to ’stoph’s query via email instead of posting here. Basically, the solution is to plot everything if you ever have a problem rendering with motion blur. It seems to be an issue introduced with XSI 6 as far as I can tell.

Eric, I’ll have to have a think about that one! I’ll get back to you. Apologies for not responding earlier, I haven’t checked the comments on this post for a while.

Cheers

Andy

small discusion on a XSI 6.0.1 fix here…

http://www.xsibase.com/forum/index.php?board=11;action=display;threadid=31156;start=5

with “Squid” comming up with this code that seems to address the problem if not a complete fix of it…

var obj; // = In_UpdateContext.UserData;
// if(obj==null)
// {
obj = new Object();
obj.rootpos = XSIMath.CreateVector3();
obj.effpos = XSIMath.CreateVector3();
obj.targetpos = XSIMath.CreateVector3();
obj.diffpos = XSIMath.CreateVector3();
obj.xform = XSIMath.CreateTransform();
//In_UpdateContext.UserData=obj;
// }

Anyway I thought It might be good to have this posted directly here….
