I'm trying to get better at AIsloppin' with multiple characters; I want to gen Karin giving a rimjob to Marina (both from Fear and Hunger) and from looking and asking around, people have suggested outpainting. I'm using SDNext as my frontend and I'm unsure about which extension would be best for my aims and how to gen with it. Nonetheless I've tried without it and I've had limited success, picrel is my best gen from the batch. If anyone is familiar with SDNext could they provide outpainting guidance and/or could they review my proompt for ways to improve? Thank you for your time.
