Can you see me now?

[Ponthieux, Joseph G. (LARC-E1A)[LITES]]

I’ve got a model hierarchy of dozens of parts under a parent object.

 

The parent object is animated via an ICE tree and I’ve added conditional behavior to the ice tree to affect things like visibility of the parent object when certain situations are met.

 

This is all working as I would like with one except. I’d like the visibility condition to propagate from the parent to the entire model.

 

Am I required to apply a setdata node of visibility for every child of the parent, or is there an easier way?

 

I seem to recall I would have performed  a branch key in the past, but I have no clue how this might translate to ICE.

Can you just make the model an instance and hide the instance masters?

Hi people,
I'm consulted for a project that would involve realtime face capture.
Something similar to this : http://www.faceshift.com/

I would like to know if some of you have ever worked with it and send
the data in realtime in softimage.

I would also like to know if there are other (nice) solutions, possibly
Softimage friendly.

Thank's in advance :)

[Ponthieux, Joseph G. (LARC-E1A)[LITES]]

Yes, that might be a reasonable way to deal with this.

 

Thanks

If you hide the master, all the instances will be hidden too.

Yeah, I know, but I can shove it off into the nether I think. That or put it in a lead box so the kryptonite rays are ineffective. J

You could also throw them in a group and drive the group's vis properties

If you check the 'hide instance master' in the visibility prop of the master object(s) the instances will still be visible.  

[Matt Lind]

Any reason why you have to use ICE to drive visibility?  I would think the established toolset should suffice.

Is there any reason you can't go with a good ol' drag&drop expression?

If you need to copy the same expression on many objects, once you have one just rightclick and Copy/Paste Animation, unless I'm missing something obvious here.

[Ponthieux, Joseph G. (LARC-E1A)[LITES]]

I have objects which are constrained to paths. The objects move down their paths with a given velocity via an ICE solution. I want the objects to not be visible at the start and end of the path, but visible everywhere else. Manually keyframing visibility in this situation does not seem optimal, especially since the objects aren’t really being keyframed.

I could yes. It’s an older asset and isn’t set up that way, but frankly that makes a lot of sense.

 

 

 

Admittedly what I was really hoping for, was that there was an ICE solution,. So for example instead of using:

 

    “self.visibility.viewvis”

 

I could something like:

 

    “all.visibility.viewvis”

 

or:

 

    “branch.visibility.viewvis”

 

or:

 

    “model.visibility.viewvis”

 

And the visibility parameter would just propagate through the selected object and down the hierarchy. Since it already is able to assume the selected object without a name, why shouldn’t it be able to assume the selected object’s hierarchy without a name?

Hmm, okay, here's a way to roughly do what you're asking:

1. Make a new customparamset while your parent is branch-selected.
   Give it whatever boolean params you need.
   
   
   
2. Set the param values via ICE with a simple SetData (self.MyProperty.MyParam), on your parent's icetree.
   
   
   
3. On the children, set an expression on your viewvis or whatever parameter. Something like:
   this.MyParamSet.MyParam
   
   Because of branch-propagation of the parent property, your paramset will appear to live on your children, so using "this" is valid.
   
   
   
4. Feel free to rightclick and Copy/Paste Animation to set the expression accordingly on all the other children objects. They should now be getting the ICE-driven values propagated correctly.

Is that more or less what you wanted?
