(I use virtual camera as camera in discord app)
In 0.1.9C it works but with d version i have this problem when you want to use virual camera
When you change windows resolution to this 320x240 it starts to work. But its so small :D
If you have special place for sending bugs ect tell me :3 i will be happy to help :3

Sorry for the slow reply, the resolution for Unity that is listed there must be the resolution set in your streaming software. In the picture, it shows that the resolutions are different. Go into the virtual camera in the streaming software and set a custom frame size, and make it whatever the program is set at, that should fix it.

But why it works on 0.1.9C without doing anything?
And i'm sorry but i'm not sure about your fixes.
I choose camera in discord app "vtuber kit virtual camera" to show avatar as camera and its works in 0.1.9C
in the streaming software you mean in my case discord? In discord i don't have any settings customs frame size ect. :/

And offtop ask its always and only give 320x240? its not so good quality :/ (its possible to change that in settings or something?)

Oh I didn't realize you're using discord. You could try manually resizing the window to be the resolution that discord is asking for. Maybe in the future I can add an option for resizing exactly. For now, if you're comfortable using the Registry Editor, you can navigate to the vTuber Kit location and set any window height and window width variables to the sizes discord is asking for.
