CH does not have live streaming support on Windows yet, but it is on the future feature list.
Would something like Spout work for your needs?
i think so, doesnt need to be spout but something that would make possible to stream in windows, like make the character animator be recognized as a game for OBS studio
Spout is ok but we are in beta and still without live streaming.
Please, could you give a more clear Character Animator path about live streaming in windows?
Windows live streaming is being actively worked on and should be available in an upcoming release.
For now your best bet is to just do a cropped screen/window/display capture like in OBS Studio. Some people have done clever things with invisible mouse cursors to drag the limbs and stuff like that.
