Questions about streaming with a Vroid model

[Lorgar Aurelian]

Hi, sorry to take your time, but I was thinking of giving streaming with a model a shot. I know this isn't the place to ask this, but what studio works best with a simple Vroid 3d model? I also would like to ask if I have the proper specs and equipment for simple streams.

not the right place but who cares
so my stance is i am not a vtuber, i do not know in detail which software(s) run smoothest and what specs you need for sure sure. i also only focus on free software and have no idea about most paid software. that said, time to answer your question (as good as i can)

first about simple vroid model: even without extra editing after exporting the vrm, vroid models can be very heavy. if you check the specs on export you see how heavy, and if you suspect your model being a issue on smooth running of tracking software, you can reduce bones and polygons right in the export tab in vroid. which is also good for models intended for vr games.

as for tracking, i think a lot of vtubers combine software and hardware for their tracking experience. commonly face tracking + something to track body and/or hands.
puppeteer programs that allow twitch integrations, props and other fun things are popular for obvious reasons.

personally i used to just use VMagicMirror, have expressions on my numpad as shortcuts to manually switch them and focus more on having keyboard, mouse and game controller tracking (or like my model actually had a game controller or keyboard and you could see it press buttons and use joysticks)

including the just mentioned one i list some software i heard of:

- VSeeFace = very popular for face tracking, needs to be calibrated and is tracking only the face from what i know. uses vmc protocol to be combined with other software. havent used it much myself. i think a big upside is that it can read vrm files but also has its own format that can be read by some other software, which actually allows for fancy shaders and effects to be added to the vroid model, which wouldnt work on a VRM model due to technical details.

- VMagicMirror = havent seen it used much outside of myself and some friends i showed it. no face tracking unless you link it to a iphone and i couldnt test that. but its simple and easy to run with a holographic keyboard and gamepad, midi controller etc included and they can be customized in texture. there also is a one time payment full version with webcam based hand/arm tracking (still no face tracking tho :'))

- VNyan = very popular vtubing software with more functionality than i could squeeze in a nutshell. but broken down its easy to combine with lots of other software, very customizable in many ways. last time i checked XRAnimator was used for webcam based body tracking, i will mention it in a moment, but theres also other options. i feel about it similar to vroid, as in that you can use it in a simple way but you can also go creatively fancy if you look into how to make your custom things

- XRAnimator = webcam based tracking that can be set to different modes, for example tracking face expressions and hands, or no face expressions but the full body instead. it also has a browser version which might be nice to check out no strings attached, but for actual streaming i recommend the version you run locally. this version also allows to record motions, which might be useful to make your own like starting/ending/break time screens

my personal opinion is if you want it simple and focus on gaming then VMagicMirror might be neat, but if you want to do exercise together with chat then a easy full body tracking like XRAnimator is a better choice. if you want everything and take something potentially more complicated VNyan is a good deal and if you arent satifsied with the face tracking even after adjusting and calibrating maybe add VSeeFace
the thing is the more software you need at once to track together with your OBS and browser sources and the game open, the harder it gets for potato specs to keep up. thats why i back then chose to ditch face tracking to have more hand movement. laptop could handle it.

all software i mentioned are free and webcam based so you dont need to buy extra trackers or a mocap suit, just a webcam.

lastly, some cool links for streamers:
https://reactive.fugi.tech this is the site people use to have a picture light up and/or bounce when someone in your discord call is talking. light and easy to visually add your friends to your stream

https://vdo.ninja this is to invite the whole 3d model of a friend in your stream. kinda low res and i dont know if that would be too much for low specs but since i dont know your specs and expectations, maybe that would still be possible.

https://nightdev.com/kapchat/ and this is to add your twitch chat in your stream overlay in obs

lowkey sorry i wrote so much. hopefully its useful to you and whoever else reads it with a similar question. then it would be okay to write half a book lmao.

Thank you so much for all the info! I would also like to ask if my PC has powerful enough specs to run some of this.
Specs:
Processor: 12th Gen Intel(R) Core(TM) i7-12700H 2.70 GHz
16GB ram
64-bit operating system, x64-based processor
It's a gaming PC, and can heat up really fast though I have external cooling available. Also comes in with a built-in camera
