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.
