This is my third Z Image Turbo lora ! ^^
I went through four failed trainings to bring you this one ;)
I didn't think this one would succeed... and so I didn't put the effects...
So... it's a test version... JUST FOR FUN AND TESTING.
--
Important details on settings below !
Also about the dataset !
--
DESCRIPTION :
Well so what is this ?
This is a background Lora with cyberpunk and city vibes. This the Z Image Turbo version.
--
City Worlds 01 :
About the dataset !
This dataset is quite old. It is a mix of 50 % realistic photos and 50 % generated stuff and anime.
Most of the captions are in tag format but as you'll see it doesn't bother Z Image.
So with it you can generate in Z Image :
real life city scenes
anime style scenes (or pixelated...)
Mix of the two above, having real life people in animation environment or animation people in real environment
Cyberpunk scenes
Futuristic scenes with spaceships
And those spaceships and buildings have a special design (Z image does a good job at reproducing the designs from the dataset)
--
Problems :
Sometimes generated images get too dark
Sometimes design spaceships get stuck in design buildings (dataset problem with some low res pics)
Some precision issues (those low res pics in the dataset...)
There are also Airships but those are ugly (no specific design in the dataset)
There are too many descriptions words (see below).... I was doing that in all my first loras.

HOW TO USE :
2 types of settings :
--
1 : Turbo
Strength : 1 tested
Steps : 9 - 20 (most of the time I used 20)
Checkpoints : Any
Adetailer : not used
Other : Instead of using the Lumina style, I used the Qwen one.
CFG : 1 or 2
Sampler : EULER
Sheduler : SIMPLE or BETA or NORMAL
--
2 : Not so Turbo... at all
Use this one if you like waiting more ;)
Strength : 1 tested
Steps : 40 - 50
Checkpoints : Any
Adetailer : not used
Other : Instead of using the Lumina style, I used the Qwen one.
CFG : 1 or 2 (2 is of course even longer...)
Sampler : DPM++ 3M SDE
Sheduler : KARRAS
About using DPM++ 3M SDE + KARRAS here :
Since Karras is unusable at a low number of steps and will produce distorted and ugly pics... After tests I found that raising the steps to 30-50 will make nice generations... and sometimes VERY nice generations.
But at the cost a slower generations...
But due to not enough time, I used Euler in most of my generations for this lora.
--
I made tests using multiple combinations between Base Fp8 version, Base Full BF16 model, and multiple text encoder versions. I used Forge NEO (easy install through Stability Matrix (choose Forge Classic package, then change version to choose NEO)), so settings might differ a little for ComfyUI.

Some more in this ZIT version :)

"airships" now become "spaceships" and "design spaceships"
haze
epic scale
massive towering (design) buildings
tiny spaceships
tiny buildings
spaceship focus
car focus
