Absolute Reality 1.8.1: realistic people, fantasy and sci-fi on SD 1.5

Topic: Models
By Captain
Published 2026-09-29
Lykon's Absolute Reality 1.8.1 handles realistic humans and wider fantasy and sci-fi prompts. Learn the creator's face-conditioning advice, settings, ISO-noise trick and creative ideas.

Overview

Absolute Reality v1.8.1 by Lykon is a fork of DreamShaper 6 tuned for realism while keeping the flexibility for fantasy and sci-fi. It handles realistic humans, backgrounds and objects well and produces varied faces when you give it context.
Creator's notes: condition faces with eye color, hairstyle, hair color and ethnicity; the model avoids a single repeated face if you play with context. If the picture is too clean, add some ISO noise.
