Attribute update during timeline scrub?

[Kenneth Ibrahim]

Hi,

I'm trying to get a heads up display to update based on an object attribute's animated value while scrubbing in the Timeline. This doesn't seem to work and only updates upon release of the mouse button. It seems that values in the AE & ChannelBox also don't update until releasing the mouse.

Does anyone have any idea if this is possible? The PolyCount HUD does seem to update while scrubbing for instance...

Thx! Ken

You need to attatch it to the timechanged event in the Headsup display call:

                    cmds.headsUpDisplay(metaHudItem,

                                        section=section,

                                        block=block,

                                        blockSize=self.size,

                                        label=attr,

                                        labelFontSize=self.size,

                                        allowOverlap=True,

                                        command=partial(getattr,self,attr),

                                        event='timeChanged')

I've done a nice neat wrap of all of this in the Red9 StudioPack, you can select the attrs you want to monitor in the ChannelBox, RMB>Red9HUD>addMonitored attr:

Be worth a look, if not just to poke into the code

Thanks for the feedback. I've already defined that event ('timeChanged') to no avail which is why I'm reaching out. Somehow I thought that would be it.

Is there perhaps a setting in Maya to have all attributes evaluated and updated while scrubbing that would then update the HUD as a by-product?

Thx! Ken

Nice looking tool and video intro. Having seen that I was able to get this working by switching from using the 'timeChanged' event to simply specifying the 'attachToRefresh' option :)

yeah it's been a god's send whilst setting up facial systems, just selecting the channels and throwing them up onto the HUD for debug.

cheers
