StellaratorMix is a realism/3D model that's very good at NSFW.

StellaratorMix accomplishes the following:

• Focus on realistic subjects in a variety of settings

• Better understanding of physicality for arranging scenes/poses

• Realistic anatomical micro details such as skin tension/folding and smaller muscles

• Strong prompt adherence with or without LoRAs

• Photorealistic materials, objects and backgrounds

• Flexible and unique faces that do not regress into pony training at higher CFG

• Defaults to high contrast, relatively dark images to solve the problem of low contrast bright images that tend to result from commonly used VAEs

Give it a try!

v3.0 Improvements:

• Proportions of facial features are now more varied, to help produce different-looking characters even at higher CFG

• CFG sensitivity increased overall; now influences details more instead of just increasing contrast

• Skin looks better in different lighting conditions

• Moles, blemishes and water droplets look more realistic

• Hands are more defined and look much better when the focus of the image

• Lighting is reworked to be more dramatic with relevant tags

v2.0 Improvements:

• Pruned size (11.3gb -> ???gb)

• Greater concept awareness

• Less frying at higher CFG

• Improved prompt adherence

• Tweaked contrast

• Lighting (skin is more responsive to ambient light)

• Better skin detail

• More expressive faces

• Better anatomy

• Better clothing detail

You can still download and use the 11gb v1.0 model if you prefer the slightly darker images that it produces. Many of the more subtle changes can still be achieved through prompting, but v2.0 has generally better out-of-the-box performance.

If you are having issues with the built-in VAE use fp16-fixed instead.
