Tips

Use simple prompts; avoid using excessive keywords like masterpiece, best quality, 8k.

No need for complex negative prompts; small negative embeddings give the most realistic look.

Add 'asian, chinese' to negatives if targeting non-Asian ethnicities.

Avoid using 'cinematic' for natural effects.

Avoid '1girl' to prevent anime-style outputs.

Too much description of the face often worsens results.

No extra noise-offset is needed but can be used optionally.

Version Highlights

Since i'm low on time i still wanted to release the RC1 of an new aproach.

  • ordinary faces, natural look, more face diversity

  • hand fix

VAE included

Recommended simple Negative for average looking output, avoid "optimizer" Embeddings

cartoon, cgi, render, illustration, painting, drawing

seems to be a bit nsfw heavy and very lose on prompt guidance for now

Natural Sin Final and last of epiCRealism

Since SDXL is right around the corner, let's say it is the final version for now since I put a lot effort into it and probably cannot do much more.

I tried to refine the understanding of the Prompts, Hands and of course the Realism.
Let's see what you guys can do with it.

Thanks to @drawaline for the in-depth review, so i'd like to give some advices to use this model.
[expand to see Advices]

Advices

  • use simple prompts

  • no need to use keywords like "masterpiece, best quality, 8k, intricate, high detail" or "(extremely detailed face), (extremely detailed hands), (extremely detailed hair)" since it doesn't produce appreciable change

  • use simple negatives or small negative embeddings. gives most realistic look (check samples to get an idea of negatives i used)

  • add "asian, chinese" to negative if you're looking for ethnicities other than Asian

  • Light, shadows, and details are excellent without extra keywords

  • If you're looking for a natural effect, avoid "cinematic"

  • avoid using "1girl" since it pushes things to render/anime style

  • to much description of the face will turn out bad mostly

  • for a more fantasy like output use 2M Karras Sampler

  • no extra noise-offset needed, but u can if you like to 😉

How to use?

Prompt: simple explanation of the image (try first without extra keywords)
Negative: "cartoon, painting, illustration, (worst quality, low quality, normal quality:2)"
Steps: >20 (if image has errors or artefacts use higher Steps)
CFG Scale: 5 (higher config scale can lose realism, depends on prompt, sampler and Steps)
Sampler: Any Sampler (SDE, DPM-Sampler will result in more realism)
Size: 512x768 or 768x512
Hires upscaler: 4x_NMKD-Superscale-SP_178000_G (Denoising: 0.35, Upscale: 2x)
