Hi everyone!
This is a video with two new examples of how I'm using kemorig in my own stream. It's a glimpse at what I've been working on lately, and I hope it can also serve as inspiration for what you can do with it with your own VTuber!
Last Monday was a special stream on Twitch for me, so I prepared new features for my VTuber. The two big ones were these:

My cel shaded style is very much inspired by Guilty Gear, and I wanted to take a stab at my own GG-style animations for Proto. In addition, I thought it would be cool to let Twitch Chat control Proto, and give chatters something to interact with during down times.
How it's done:
This feature is set up as a 2nd Stance Group (the 1st is the main group I use for standing, sitting, etc while streaming) with a Neutral, Crouch, WalkForward, and WalkBackward stance.
I have an additional Toggle-Interaction to enable Fighting Mode. When Fighting Mode is not enabled, the avatar's Anim Graph toggles off the slot that Fighting Mode uses.
The stances are bound to hotkeys, which streamer.bot (a program for interacting with Twitch) triggers in response to chat commands.
There is a little bit of blueprint script in my avatar to move him, automatically switch back to Neutral stance, and stop him from moving off the side of the screen.

I stream a lot of retro games, and wanted to stream off my PSP for the first time! It was an opportunity to do something special with Proto, and I had the idea to literally have him holding a PSP with the illusion that we're looking over his shoulder.
How it's done:
The PSP sitting pose is an additional stance added to the avatar's main stance group. (not shown in the video: it also has transition anims authored to/from other stances).
When entering or leaving this stance, the avatar's Blueprint toggles visibility of a skeletal mesh (the psp model), which is attached to a bone on the avatar.
The zoomed-in PSP framing the video feed is a rendered image from Blender (it does not animate).
I'm really happy with how these features turned out. Plus, they help me improve kemorig, as I run into little annoyances here and there while implementing them.
Hope this was interesting, and can't wait to see more of YOUR creations with kemorig!
