Face rigs

[George Schermer]

Hi all,

I have a friend who is starting up with XSI and he asked me if I knew of any facial rig tutorials or free rigs that could get him started.  I'm not really up to date with that stuff so I was wondering if anyone on the list had some recommendations to get him started.  I'd also be interested to see these as a refresher course since I've been away from XSI for a couple years.

Thanks!
George

[javier gonzalez]

There is a free rig in this online school, Malcolm.

I personaly like this shape+GUI tutorial a lot:

That one's really showing it's age now! I do it all in ice these days, haven't got round to updating yet though.

Adam Sale did some more recent ice face rigging stuff:  http://vimeo.com/26980409 

And Paul Smith's videos were recently posted on si-community, though I'm guessing he has also updated his workflow in ice since:

Hey Matt, 

would be nice to see some ICE video showing your setup updated.. I got curious now ;)

[Renato Polimeno]

I mean, are you doing all the coordinate controls (XY, -XY, X-Y, -X-Y) all in ICE ? 

How do you limit them ? 

What about triggering the shapes (average maths or something different) ? 

Are you using the standard shape technique and stack or shapes are ICE deforms aswell ?

Sorry for all those questions, I might take a glass of water to slow down my rigger-part-of-the-brain :P

[Matt Morris]

Yeah all the controllers are linked in ice and limited via rescale/clamp nodes, very basic stuff, I'm still getting my head around this node malarky! No weightmaps, just ice attributes for L/R morphs based on the X-axis.

Triggering shapes is just linear atm, but will look into adding correctives via distance between points and so on.

I'm using Ahmidou's awesome arc interpolation compound for eyelids, and some simple cage deform stuff, looking into adding more ice deforms.

It takes a while to setup but if you do it modularly (brows, eyes, mouth, cheeks etc) then you can reuse it to apply to a new rig pretty easily - so build your shapes, test them in the shape manager, then delete the evil cluster shape combiner and drag and drop the compound, and it links everything up. No more mixer clip connection pain thank god!

Still all shape based though. I'm Looking forward to what Jeremie comes out with for the face components of GEAR! That's going to be pretty damn sweet.

Going back to the first post, there's a few nice rigs here too:  http://cjcow.net/mark.html

Here is my ancient (softimage xsi version 6.5) rig with synoptics:

Thanks for all of the replies.  These look great!

[George Schermer]

Thanks!

[Michal Doniec]

Yes, there are quicker ways to mirror weightmaps now with ICE than
what we were using years ago, but I think it's still quite valid
tutorial Matt.

On the side note, during last couple opf years, I haven't really made
a rig based on "Osipa" method - reason being animation wants sliders
and total control, it's all FACS absed as well.

Not an easy or quick read, but has some interesting stuff.

I used the book stop staring and was able to do my rig using softimage. You need to have a good handle on XSI and Maya to do that though.

A question to those in the know - how much of a slow down would there be using say, 24 volume deformers as opposed to an extra envelope and 24 nulls driving the deformation that way?

--
www.matinai.com

[Alan Fregtman]

An envelope would be theoretically faster as it's 1 operator instead of 24, but it's worth investigating. Maybe I'll try to benchmark this weekend.

[Eric Thivierge]

Is the envelope operator multi-threaded?

http://www.ethivierge.com

[Grahame Fuller]

Yes, I think it's the only native deformation that is multi-threaded. (Maybe also cage because it's essentially the same thing.) A lot of work went into optimizing envelopes many versions ago.

Yes the Envelop Op and the Cage Deform Op are both multi-threaded. But the Envelop Op is the only one using GPU acceleration (if you keep the "Allow Approximate Operators" preference On and don't add other deformers on top (except if the other deformers are Envelop Ops as well).

"except if the other deformers are Envelop Ops as well"

Not that I really want to do that ... but just curious... how do you get two envelope ops on a mesh ? scripting only ? 

[Grahame Fuller]

You can put them on separate clusters, even if all the clusters contain the same points.

Having had a chance to test volume deformers out, I'm really liking the effect - a moving influence instead of a painted area. 

I've tried building it in ice and am getting somewhere, but still some issues with parented rotation etc - has anyone tried to replicate the volume deformer in parent mode in ice? I'll post my failures later if anyone's interested...

Thanks Eric, I went the long way round doing all the transformations in srt - appreciate the ice 101!

 

Second question then - is there any way to set this up for a group of parent nulls and a group of transform nulls?

Haven't really done any tests using groups with this type of setup.

That said, you can't have a second set of envelope weights without a second EnvelopeOp, correct?

I've used a second (muted) envelope before to have weights to control an ICE effect with. It's easy to read the percentages for a given deformer out of the weights, so you can treat it like a weightmap at that point. Envelope weights are like multiple weightmaps in one, in a way.

--

[Alan Fregtman]

But you can't have multiple envelope weights without multiple envelope operators, correct?

I used a second muted envelope before to control an ICE effect. In a way, env. weights are like multiple weightmaps in one and with ICE it's easy to read the percentages for a specific deformer.

Hi all,

I have a friend who is starting up with XSI and he asked me if I knew of

any facial rig tutorials or free rigs that could get him started. I'm not

really up to date with that stuff so I was wondering if anyone on the list

had some recommendations to get him started. I'd also be interested to see

these as a refresher course since I've been away from XSI for a couple

years.

Thanks!

George

Just as a quick follow up - I tried with around 20 volume controllers and was starting to get some wierd behaviour (2 volume controllers on the base mesh wouldn't rotate and scale without flickering) plus long delays when painting weights on the original mesh. Rebuilt in ice (thanks eric) and the whole thing runs much much smoother. Unfortunately didn't run any frame rate tests but will be sticking with ice in the future.

I still have one wierd issue - I have a base mesh with ice shapes and a deform mesh with ice secondary deformers on. With the deform mesh hidden I'm still getting minute delays when painting weights on the base mesh - when picking a new bone to paint with for example. It seems like SI is still doing some kind of calculation on the deform mesh even though its hidden and the original mesh doesn't relay on any data from the deform mesh - very confusing. If I delete the ice trees on the deform mesh then I can paint fine on the base mesh.

i believe  just the act of having the 'get data' node referencing your object is causing the slow down. enoch could probably share his experience with mixing ice deformation with a facial rig and experiencing the same issue. all in all its the nature of ice.
