Instead of telling you the things on the original Hyenid that are available on the Synth version, let me tell you what ISN'T:

• Fishnets
  
• Eye shapes (as in the physical eyes, shapekeys related to the eyelids are there)
  
• Body fluff
  
• Muscular Chest shape
  
• Breathing and nose twitch
  

Anything that is not on that list, it's probably supported in the synth version, so in other words: Every feature on the original Hyenid that wasn't listed above is supported in this version!

Roughly 20mb of VRAM can be shaved off by removing the emission map from the clothing and pin materials in the Hyenid's materials, as it is unused by my edited menus.

INSTRUCTIONS:

Download the Hyenid from its OFFICIAL store page and download its dependency shader Mochies.
Download the Synth Hyenid package and free version of Poiyomi found in the downloads after purchasing.
Open the VCC and make a new project.
(Optional) If you plan to use the Face-Tracking version, make sure you install VRCFury and Jerry's Template module into your project.
Open your new project and import the following IN THIS ORDER:
Mochies Shader
Poiyomi Shader
Synth Hyenid
Hyenid
The Synth Hyenid package MUST be installed BEFORE the original Hyenid otherwise it WILL break. This has to do with Unity GUID garbage, so just be sure you install the original Hyenid last.
Under the "Tools" tab at the top of the Unity should be an option called "HighCD" inside of there is a patcher which will open a small unity window where you just need to click a button.
In your project assets, inside "Assets > HighCD > Hyenid" should be a scene file with the Synth Hyenid already set up.
Ready for upload.
