Hello! I am currently facing an issue with this wonderful little app. I have my character set up in the app and it moves when I talk, everything with that works just fine. However when I try importing it into OBS studio as a game capture source, and then I select the specific veadotube min.exe window, it just displays a black screen. I have found no way to fix this, and everyone who's shown me have their gamecapture working just fine as it displays the pngtuver in OBS.
this usually happens with laptops, try explicitely telling obs to open with the dedicated gpu (right click on the exe > run with graphics processor > select the option that isn't integrated graphics). if that doesn't solve it, i'm not sure yet what could be :[ it's certainly something with obs though
