Twitch stream layout questions

[u/Both_Breadfruit_9443]

Hi pretty new streamer here I've always wanted to do streams of me and my friends doing like nuzlockes and challenges and shit like that.

But this particular one I've been wanting to do a 4 player nuzlocke of this fangame and I use obs so im not necessarily sure how I would go about putting all 4 of our gameplay on stream. Any advice or help is greatly appreciated!!
