Hi guys!

I'm a beginner with apex graphs and for my rigs I usually can do everything with the autorigcomponents, but for my project I should do a cartoony eye where the eye is not spherical but squashed a little bit. I found some tips in one of the Tumblehead guys Hive video but it was still in 20.0 and they a did a very manual setup. Since than I saw that they added a lattice node to the graph editor but I'm really stuck on how to use it, does anyone had any luck with it?

Thanks for the help!

geo::lattice callback has the same requirements as Lattice SOP, meaning the restgeo and deformedgeo have to be compatible with geometry produced by Box in Polygons mode or Bounds SOP, with Divisions enabled and Divisions have to match among them and the Divs inputs

here is a file with 2 simple examples
1. mimicking Lattice SOP

2. self contained lattice deformation derived from the geo bbox inside of APEX, for simplicity hardcoded to default 3x3x3 lattice

however you can also pack the rest_lattice geo into the rig weighted to some bones and use that and its deformed version within the rig or deform in different way within APEX itself
or mix and match different approaches as needed

Thanks you very much!

This helps a lot, would have never guessed this method. I had problems with how to add the lattice geo into the graph, but both methods are really nice solves thanks again!

This is really cool thank you so much for sharing!

I was wondering how to get the cartoony eye setup in apex. I checked your example and a couple questions I have is how do you pack this up for apex stream. And also how do you bind the lattice to joints in the skeleton as you mentioned, should I just use the tet embded to biharmonic bone capture workflow for that?

I haven't seen an example of the apex invoke graph being used before so I think that's why I'm struggling to figure out how to pack it properly for apex. As seen in the picture attachment I inserted, I tried doing it with pack folder node like I normally would but I feel like I'm way off.

If you're using the Autorig Component workflow, then you'll (currently) need to add the set up as a component. Max Rose has lots of videos on how to rig in APEX so I highly recommend them (eg. https://www.youtube.com/watch?v=Fxn_4TV3kNc [www.youtube.com] for a live stream on APEX Script, and generally check out his channel: https://www.youtube.com/@maxrose8845/videos ).
