Ivy (Deadlock) enhanced rig

Here it is: the Ivy rig I've been working on for the past 2-3 weeks now, which is also the very first rig I've made in Blender (already made 1 or 2 in Maya in the past).

It has a full bone based advanced face rig (no shape keys), FK/IKs for the limbs (wings included), and a lot of control capabilities akin to what I'm used to in the animation industry while also suited to my preferences.

Things to keep note:

- The rig is far from being perfect. Several of the main controllers can break very easily when pushed too far (eye lids in particular), hence why there are tweakers to make readjustments (all manual, no automation). Same with weight paints and the custom hand painted normal maps in some areas.

- It uses Rigify as the base for the body, so all functionalities you can expect from it (FK/IK switches/snaps, follow spaces, tweakers) are in there. But I also made some heavy reverse engineering to fix some of its short coming (like the hips behavior).

- It was made in Blender 4.4

- All the rotations are in euler, no quaternions. You can change it if you want but I prefer to stick to euler since it makes polish in the graph much more efficient.

- Some controllers have special properties in the Item/properties tab like the Hat, its leaf, Eye aim prop bones on the hands and the ponytail having switchable follow spaces, and the specular in the eyes having toggleable visibility.

- Tusks drive parts of the lower lips for easier posing

- Main finger ctrls are ok-ish for posing but I recommend using the tweakers instead (still debating if I should even keep them in the first place. At least they're easily hide-able with the dedicated layer)

- I only tested the rig in a vaccum so I have no idea about how optimized or light weight it is with other characters. Try disabling shaders and using Simplify if your performance tanks a lot, and rely on Viewport renders for timing (like we do at work).

- Almost everything was designed so that you can very quickly reset the rig by just zeroing out pos/rot/scale attributes (which have dedicated hotkeys).

- You can use sth like Jiggle bones addon for the hair and ears.
It's a very advanced rig, not easy to use (especially w/o a pose library which I plan to make for a future project), but I find it on par with what people use on mid/high end feature films and a lot of decent TV series (which is above average of what you'll find on the internet, and trust me I've seen worse in the industry).

Some rules:

- No NSFW

- Do not use for commercial purposes

Let me know of any particular issues and I'll see if I can fix it on Ivy or if I'll use it as a learning experience for the future (I'm no pro rigger).

Big shout out to @hisanimations for the optimization and making it optiploy compatible.
