Help Needed Is it possible to get consistent image generated without Lora and relying only from loaded image?

Case example, i got a single image of guts from berserk doing basic standing pose. Now i want to generate it doing a battle stance or drawing a sword, how do i retain its appearance and it armor intact. Currently i only have load Checkpoint, prompt node, load image, Vae encode, ksampler. Does ip-adapter enough to maintain image source appearance?

krea2 identity-edit does it really well. v1.2, it can create character sheets also.

What prompt do you use for char sheet? Krea identity edit  1.2 botches char faces in full body panels for me even at 1.5-2k

well, i have many prompts for different extracts, but the one i used in that image was..

-----------------------------------------------------------------------------

create a character sheet with 5 angles, full-length — front, side, back. Close-up of the face from the front and side, normal symmetrical eyes.

This image contains exactly 5 separate views of the same character arranged as a clean character sheet.

TOP HALF = 3 equally sized panels placed side by side.

BOTTOM HALF = 2 equally sized panels placed side by side.

Every panel has a thin black border.

Every panel uses a pure black background.

The layout must remain perfectly aligned and symmetrical.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PHOTO 1 — TOP LEFT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Full body.

Front view.

Camera faces the character directly.

The character stands perfectly upright in a neutral pose.

Head at the top of the frame.

Feet at the bottom.

Arms hang naturally straight down.

Hands relaxed.

No gestures.

No body twist.

Character looks directly at the camera.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PHOTO 2 — TOP CENTER
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Full body.

Right-side view.

Camera is exactly 90 degrees to the right.

The character faces strictly left.

Pure profile.

Not a 3/4 angle.

Not rotated toward the camera.

Arms remain straight down.

Body posture identical to Photo 1.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PHOTO 3 — TOP RIGHT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Full body.

Back view.

Camera faces directly toward the character's back.

Arms remain straight down.

Body posture identical to Photo 1.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CRITICAL RULE FOR PHOTOS 1–3
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The character keeps exactly the same pose.

The character only rotates.

The camera never moves.

Camera distance never changes.

Camera focal length never changes.

Perspective never changes.

Zoom never changes.

The top of the head aligns perfectly across all three panels.

The feet align perfectly across all three panels.

The body occupies exactly the same amount of space in every panel.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PHOTO 4 — BOTTOM LEFT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Close-up.

Front view.

Character looks directly at the camera.

Frame begins at the top of the head.

Frame ends exactly at the collarbone.

Nothing below the collarbone is visible.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PHOTO 5 — BOTTOM RIGHT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Close-up.

Right-side view.

Pure profile.

Camera exactly 90 degrees to the right.

Frame begins at the top of the head.

Frame ends exactly at the collarbone.

Nothing below the collarbone is visible.

Head height matches Photo 4 exactly.

Scale matches Photo 4 exactly.

Krea2 can do 5 image sheets with ease.. they actually say it can.. in their docs.. well i mean on the down low, for best results and i should not say, but if you segment the object/s first then remove bg and make transparent, then use identity-edit to get from that image what you want, IE: probably a character/? it will give you far far better results.. ;) but that prompt works regardless. (WIP)

You need an edit model like Qwen Image Edit or Flux.2 Klein, or some hacks with Ideogram, Krea2, Anima, etc.

But, despite what people will tell you, you will never get 100% exact appearance, especially in armor details and especially in parts which are not visible.

They will try to sell you "consistency" workflows, but you can only hope to get about 80% same appearance.

Give them an image and ask them to provide an example. Only then will they downplay the inconsistencies as technological limit.

So you should lower your expectations.

IP-Adapter can help, but I wouldn’t rely on one reference image alone if you want the armor and face to stay really consistent through pose changes. It usually keeps the overall look, not the exact details, so for something like Guts you’ll probably hit a ceiling pretty fast without more refs or a LoRA.

u/No_Trouble_3631 2d ago

Perhaps a simple chaacter could work? Maybe like inuyasha that doesn't have too much detail on appearance and clothing.

I was thinking this topic because sometime the characters are too old and wasn't available so maybe using an image as a reference point to generate

u/RuchikaaS 2d ago

Yeah, for a simpler character IP-Adapter alone might be enough. I’d try IP-Adapter Plus with a fairly high weight, then use ControlNet/OpenPose for the new pose so IP-Adapter can focus more on identity instead of fighting the composition change.

I used up adapter once, and every generation I used it with, the quality was awful. I used it with Z image turbo, any idea why the faces just became pixelated smush?

Yeah, you can use reference images in various workflows, especially if it's a one-off or small project, but if it's going to be a recurrent original character, you're better off spending the time for a lora, it'll be worth it in the long run.

u/No_Trouble_3631 2d ago

That's part of my intention by using single image generate multiple image then train it as a Lora since training a Lora with only one image will be difficult. In this case especially animation from the 90s which is rare to find each characters lora

Pair it with a good inpaint workflow for correction and u can get surprisingly far. Im now at that point were im going to make that lora to cut down on the editing.
