Not the author of the model. Description below, sadly nothing for v4.5 but seems like an improvement on the previous versions so feel free to test and post.

This is my observation so far:

• does really well solo images, very good mixed semi realistic, nice details, and simple prompting.

• score_9, score_8_up, score_7_up - seem to do the job to output what i want without abnormalities,

• close ups are better than full models, detail loss on full view objects, unless you add a lora but feel free to experiement or read the original creator's description below.

• it picks up race quite well race(at least Asians)

• Using Euler A, 30 steps CFG:4, i am yet to try other samplers but this one works well.

From CIVITAI

v3 :

Better backgrounds, sharper images, improved contrast and more detailed images.

Eyes improved, on 20+ steps.

v2 :

A pinch of more realism, and improved faces

For best eyes and faces use Adetailer.

CFG Scale : 5-10

Sampling steps : 20-30

Sampling method : DPM++ 2M Karras ( Euler a also works)
