AvaTAUR - Fully Featured Quadruped
1,350 Animations | 1,250 Animation States | 5,400 Animation Transitions | 235 Blendshapes | 28 Hair and Body Features | 90 Menu Options

This avatar includes many types of features and options that you may recognize and many you may have never seen before. Everything included is built from the ground up specifically for this model. This package includes everything you need to get a walking, talking, posing Taur into VRChat!
Normally this pack will NOT include any clothing. We have many clothing packs in the works that will be released over the next year. However, until 7/1/2023, we will be including a T-Shirt, Tube Top, and Lanyard for free! They are even themed for the Furality Sylva event!
Key Features:

Custom Walking System with toggle-able grounders for the legs.
14 Pre Built Poses - Laying, Sitting, Reaching Up, Lounging... and generally Tauring Around
"Ghost Mode" gives you the ability to Astral Project out of your AvaTAUR, but still control and pose from a distance.
Fun Contacts! - Boop, Head Pats, Butt Scratches, we've got it all.
Dexterous Handpaws - You can control the front legs with your hands. This is compatible with finger tracking for Index users! Gesture with "Thumbs Up" > "Fist" > "Open Hand" to swap control! If you want a different combination, it's easy to change, and if you don't want it at all, disable it in the toggle menu.
Backup Cam Included! - You can toggle on a HUD view of your hind end to see what others are up to back there.
More Camera Options - A 3rd Person Camera (Desktop Only) and a HUD based 1st Person Camera when you are in Ghost Mode.
Fully Integrated Full Body Tracking - The front legs and hips are directly controllable with Full Body Trackers, additionally, in some poses and modes you can also control the hind legs with your real feet!
Face Tracking - This package includes all of the necessary blendshapes for both the Sranipal and ARKit lip and eye tracking. (Not Fully Configured Yet)
Let Others Control Your Butt! - Yep, there's an option to allow someone else to take control over your butt and hind legs.
Clothing System - 90+ Clothing Options have already been prepared for this base and will be released in packs across the next year. (Not included in this pack) If you want to use your own clothing, you can use this system as a template to easily setup outfit toggles and breathing animations.
Choose Your Size! - You can adjust your overall scale with a slider and small reload. Additionally, you can change the size of your hands, feet, head, tail, bellies, and breasts.
Typical Features have not been overlooked! You can turn on a flying collider, puppet your tail/ears/toes/tongue, make faces with the hand gestures... ect.
Squish Bones - Oh yeah, those were just released, weren't they? We've got them on noses, cheeks, rump, and bellies!
Custom Sit Poses - Time to answer the age old question of "How to taurs use chairs?" I'll let you discover this one for yourself. There's even a menu for choosing your favorite!
"I want to ride the Taur!" - Yes, they can ride the Taur, if you allow it. However, these seats are a VERY different from your average VRChat chair. First, they are smoothed, giving the passenger a much more pleasant experience. Second, each passenger has a small elevator panel in front of them that they can activate to choose their own sit height and rotation!
At the very base of it, this avatar is nothing more than a standard human according to VRChat. Unity and VRChat recognize the upper body and front legs as a (slightly odd) humanoid. This means that MOST additional features and addons will work normally with this avatar. As the community begins to experiment with the AvaTAUR, I will compile a list of packs that are known to be compatible with this character.

But how does it work?
VRChat is given an invisible skeleton that it can have free reign over. A second invisible human is then loosely connected to VRChat with constraints. On the hips of this avatar, a "spine/tail" is connected and animated. Another invisible human is then anchored to the end of this "tail" and given animations and Final IK's VRIK component to make it walk and keep it's feet on the ground. Finally the digitgrade legs are connected to these humans with Final IK's LimbIK component.

TLDR: Three and a Half Humans in a Taur Suit.

"VERY POOR"?
Yes, even by default the AvaTAUR is rated "Very Poor" by VRChat's standards. Due to Polygon count alone we will not be able to escape this ranking, but even if we decimate, we are using enough Physbones and Contacts that would push us back into Very Poor anyways.

Unfortunately we cannot just remove these without removing features as well. For example, we are calculating the velocity of the hind legs via a set of 9 contacts and a few constraints, we have a higher polygon count on the base mesh so we can have the ability to change breast sizes without too many jagged edges, and we are using a lot of physbones to keep the animations leveled when you are directly controlling the back legs.

We've still put a lot of hard work into optimizing it as much as possible. Every feature of the AvaTAUR is disabled until it is needed, the materials on the meshes have been limited and packed as much as I can manage to help reduce texture size. and many layers of the animation controllers actually manage multiple aspects of the character.

However, you will notice a frame drop when you load into this model. This frame drop seems to be related to the animation controller and is mostly for the person wearing the model, but others will see a small drop as well.

In the past 4 months, we've managed to recover around 15 FPS due to various optimizations, but we are still far from ideal. I've decided to release this base as is with this disclaimer regarding the frame drop. Maybe this is something that will be improved in the future, maybe not. Either way, if you plan on purchasing this base, you should be aware of this and expect it.

Quest Compatible When???
Currently, this base is NOT Quest Compatible. Quest does not allow for Constraints or IK Components, and these are essentially the glue holding my "Three-and-a-Half-Humans" together. Theoretically, we could decimate the base model and then JUST drive it via animations and physbones. It wouldn't look the greatest... but it might work.

For now, the official stance is "Not Quest Compatible".

Why is VRChat so Angy?
It just does that sometimes...

When you go to upload, you'll be met with a few warnings.

"A Material has custom shader keywords" - This avatar includes a few custom shaders for UI style elements. Specifically I am animating the falloff radius of the screenspace shader for the Desktop 3rd Person Camera. If you REALLY want this gone, you can delete that and then set the "Green Wireframe" and "Red Wireframe" to standard shaders.
"Audio Sources found" - Well... yeah, I'm using sounds for the "Pop", "Elevator Music", "Purring", and "Stretch". If you want these gone, go ahead and delete them.
"LowerArm is not the first child of UpperArm" - This is a naming convention issue, I have not noticed any issues with it, but if people report problems, I can update it so VRChat doesn't complain.
"Stations found" - There are 3 seats on the AvaTAUR. Two normal passengers and one for controlling the hind end directly. Best seats in the house! But if you want them gone, you can delete the "Stations" object under "Scripts".
"The angle between pelvis and thigh bones should be close to 180" - I've seen MANY avatars with this exact same issue. Once again, I haven't seen any issues with the current setup, but if people report issues I can finangle with it to make VRChat happy.
TLDR: Don't worry about it, just hit "Build & Publish"
