Bird Wing Animation Rig

[zoki]

Hi

does anyone have any experience rigging a birds wing so it folds nicely and all the wings fold properly?

I have odf from stuart little and is very good but I have problems doing the same in Houdini?

We did some of that stuff for Disney's "The Wild" (when I was at CORE)... it was rather difficult, we tried a few different approaches and wound up just setting a skeleton pose manually and blending the bones rotations and goals into the pose position... If I recall correctly, we still had to do a good amount of corrective work on top of that (smoothing skin problems, mashing feathers around until they fit nicely). We studied the Stuart Little stuff as well but I don't think we used all that much from it... the anatomical placement of your wing bones will be pretty important though.

the smashing of feathers was for a different reason.. i won't go into.

what you will have to do is a number of blendshapes to help put your wings from a flight position to a tucked on the body position.

like jason said your bone positions is important but it also depends on how you are doing your feathers.

Hi

thank you for replies!

I know that is a difficult one

I will think about what you guys said,but it seems it wont go without later cleanup and tweaking

Yeah I'll bet they killed themselves doing the wings on that twink... "custom code" in Maya no less (picturing a ring binder full of mel scripts)... <shudder>

I've still got it on my to-do list, to try and come up with a bird-wing rig that can fold up reasonably well...there's gotta be a way to do it somehwat elegantly, with a few clever rigging tricks and not a mess of blendshapes and junk... maybe starting with a simplified bat-wing concept first, just skin and avoid the stacking of the feathers for now...

excactly this is how I am starting

I am doing guide skin

with nice parametrization so later feathers can be instanced on

once this skin folds nicely I will proceed with feathers
