How to Do Eye Control for VRChat:
In the right hand panel, click on "Add component" type in "Descriptor" find the one that says "VRC Avatar Descriptor" put that in. Scroll down to find "Eye Control", click on the little circles inside each one and type in "Eye". Look for what ever you named your eye bones (Eye.L or LeftEye)
Once done, click on the "edit" or whatever it says on the side of the menus with 0 0 0 and click on each one. Adjust the eyes in rotation to look forward, left, right, up and down.
For a "Jaw Toggle" (Not sure what you mean, but I will try):
If you made a jaw bone (its not really a toggle) grab your model, click on select in the right hand menu towards the top, make it humanoid, go to configure, fix what ever needs to be fixed, go into head, same thing, but where it says 'Jaw' add the jaw you made for it. (This is here if you didn't make any visemes, you DO NOT NEED IT if you made visemes)
For Ear Wiggles:
That is an animation YOU can make in Unity.
See the bottom panel in the middle? That's for animations.
Click your model in the left panel (hierarchy) go down and click 'Make animation' (It will automatically make a controller for your model)
Name the animation what ever you want, put it where ever you want.
Find the ear bones you have made.
Click the red dot in the animation thing at the bottom to start recording your actions.
Rotate the ears however you want, don't be afraid to make mistakes, we all do.
Keep doing that for every tiny movement, be sure to move the thick line in the animation tab below to another number so that way it knows you did not mean to make the adjustment for the same frame. Ex: You wanted it rotate 23 degrees up, for the next frame you wanted it to go 60, but you put it in the same frame, so now the same frame is 60 instead of the 23.
Just keep playing with it until you get it how you want it.
If you want to make it a toggle, that's a different thing. You can either make it a bool or an int.
I reccomend bool for it because its an on off switch. To do that make a parameter. (Right click, go to VRChat, go to avatar, and you will see two menus, you want both. Rename the para and menu to your model's name so you know what is meant to be the main menu: "AvatarName Menu" "AvatarName Para".
Go into the para, hit the plus button. Call it whatever you want, set the type to Bool.
Go ahead and make an FX which is just an animation controller. (You can copy the one you made before or use the one you made and just rename it to FX for better clarity)
Go into the TOP part of Unity (NOT THE TABS AT THE VERY TOP just above the window your model is in) and click on 'Animation'
You will see a few things, don't worry. Go into the tab that says 'Parameters'
Call it the SAME name you called it when you made it in your avatar's para. (The name is case sensitive so it needs to be EXACT or it won't work)
Be sure to make it Bool too.
Once done, go back to the other menu next to the 'parameters' tab (The one that had the hand stuff in it)
Click the plus button. Call it whatever you want, this is not case sensitive, so as long as you know what it is, its fine.
Right click inside the middle window, create an empty, drag and drop the animation you made next to it. Right click on the empty animation, make transition to the animation. Do the same thing to the animation, but to the empty. Like this: ===> <===
Click on the white arrows for each one. TURN OFF has exit time.
Go down to where it says "Transition" and change it to 0.01 for a faster switch. Do this for both.
Go down to where you see the yellow warning sign. Click the plus button (I think its a plus), find the thing you created in there (The ear wiggle para). Click on that. NOW for the first arrow on the bottom going TO the animation FROM the empty, make that TRUE.
For the arrow on top going FROM the animation TO the empty, make it FALSE.
NOW go back to where you made the "AvatarName Menu" and "AvatarName Para". Click on the Menu, click the plus, (you can do this for a sub menu if you want, but for now we're doing a toggle), Name it whatever you want, it is NOT case sensitive, change the type to toggle, click on the para type and find the para you made for the ear wiggle.
After all of that go back into the avatar description in the right hand panel, go down where it says 'Playable Layers' put in the menu and para you made in the places that say "Menu" and "Parameters". Go down to where it says "FX" and put in the animation controller that has your animation. (Be sure to remove the controller from your "Avatar Controller" at the top in the avatar descriptor if you hadn't already.
Now it should work. If it doesn't, then all you need to do is go back in, make a blank animation by going to ear wiggle again, (this is a new animation btw), hit the record button, and just wiggle it up one and then put it back at 0 for both of them (because the ears are separate and likely in the same animation anyway. Yes you can move two things at once in the same animation). Why are we doing this? Because Unity is a bitch sometimes and wants an animation with numbers in it. This animation you just did will be your OFF switch for the ear wiggle.
Go back to the 'animation' tab where you did the bool thing. Go to the empty. Click on it. See on the top right in the side panel where it says "None". Find the new animation you made and drag and drop that sucker in it. NOW it should work. Yay.
