An Analog CRT & Retro Cyberpunk Aesthetic LoRA
This is a specialized style LoRA trained to inject authentic analog decay, retro CRT monitor physics, RGB chromatic aberration, and vintage broadcast interference into your generations.
Unlike clean digital render models, this checkpoint transforms crisp digital assets into gritty, atmospheric photographs of physical CRT displays and analog media.
Suggested Krea 2 Turbo Settings
Model strength: 0.1-1.0
Samplers/schedulers:
dpm_2_ancestral / ddim_uniform (or sgm_uniform)
exp_heun_2_x0 / ddim_uniform
euler / beta57 (or beta)
Also note that you can push the model strength to 1.25 as well. I think beyond that gets a little too distorted, but try a variety of LoRA strength values! You can really dial things in to taste.
📺 What It Does Best
Integrated Hardware Decay: Adds authentic horizontal scanline tearing, phosphor glow bleed, and rolling electromagnetic interference.
Color Fringing: Generates organic neon cyan and magenta RGB ghosting and chromatic aberration.
Text & UI Fidelity: When dialed to the sweet spot (0.6–0.8 strength), it preserves complex typography and UI elements while wrapping them in raw retro atmosphere.
While Krea 2 base model does understand the elements of this style, the effects it applies look a bit "pasted on top" in a fake way. This LoRA integrates those effects into the image. Krea 2 by itself also doesn't do a good job with the glow or haze from an old CRT screen, it's often missing. This LoRA corrects the overly digital, sterile, and bright look from the base model.
💡 Advanced Tip: Negative Strength (-1.0)
Want a completely different look? Try setting the LoRA weight to a negative value like -1.0.
Instead of adding analog CRT decay, inverting the weight acts as an "anti-CRT" filter that strips away the style bias. It forces the base model to pivot toward hyper-detailed, clean chrome/glass material textures and sharper structural geometry while keeping the chaotic glitch borders intact.
Description
This version used a batch size of 1 and was trained to 3000 steps. It was a tough choice between this and another version that used an effective batch size of 16 trained to 2000 steps. This version was working a little better, especially when applied at higher strengths.

Was looking for a Vaporwave LoRA for Krea. Really good work on this one!
This is a great style for pushing Krea2 past its comfort zone with analog glitches. Thanks for making this!
I have to ask because I couldn't get it to work right, how do you prompt for the various CRT/VHS effects? The ghosting, the scan lines, the "corruption" as seen in your "ABYSS" image, for example. I couldn't get those to show up properly.
Try adding descriptive words/phrases like "horizontal analog scanlines" or "static noise" or "chromatic aberration" or "VHS tracking errors" - I try to include the prompt in all the images I post, so you can take a look at that one specifically and the others. "CRT" is also good to add in there of course or "failing CRT monitor" even. The base Krea 2 model does understand many of these effects, but it renders them with a much cleaner/sharper quality that makes them look placed on top and fake. They don't blend in or really feel part of the image itself. Try different sampler/schedulers too as those can have a big impact on the image. If you find the base model fighting too hard, pulling the opposite direction towards a clean pristine image, you can increase the strength of the LoRA.
@HackAfterDark Thank you!! I'll try some of those suggestions out! What I got can be seen in some of the effects in the "come over" images I've posted. But it's mostly just text effects I got
@Vera97Â I took a look, that was a tough one! I'll sometimes go get some help from AI and so after I tried a few tweaks to your prompt for that "come over" image without it being overly strong with the LoRA effects, I asked AI. It returned an adjusted prompt (much longer) that should really bring out the effects. Try this one out and adjust to taste:
A raw, retro-futuristic analog composite poster, violently dominated by the catastrophic physical decay of a failing CRT monitor, actively degaussing and misaligned. The entire image has the unstable, grimy feel of a dying screen, with visible physical RGB phosphor triads separating across the dark areas and a severe, physical screen-door aperture grille effect (scanline shadow mask) overlaying all elements.
At the top of the frame, the text "CYB3RD" is rendered, but it is not a clean digital font. It is heavily pixel-sorted, data-moshed, and consumed by severe red, green, and blue channel separation, causing the letterforms to bleed intense, fragmented neon colors.
A woman with light hair and a leather jacket sits in a dark room, viewed through the corrupted screen. The projected text "come over" is not a clean projection; it appears as burnt-in phosphor ghosting (image retention), distorted and smeared by severe red and cyan fringing. This ghosted projection overlays the wall behind her, along with harsh, irregular shadows caused by the electromagnetic interference rolling across the tube.
Anchored to the bottom-right corner, large, bold, retro-futuristic overlay text reads "NEW!!!". This text is physically distorted by extreme, independent chromatic aberration, making it vibrate with intense cyan and magenta separation, separate from the main projection. Underneath this text, rendered in a blocky, corrupted CRT scanline font, the text reads: "SEE HER IN YOUR DREAMS", stacked vertically.
The composition is heavily layered with authentic, physical VHS tracking tearing lines, horizontal jitter, severe rolling distortion bands, and scattered electromagnetic static noise and snow. The edges of the frame show significant head-switching jitter and noise artifacts, simulating a damaged tape being played on a dying monitor.
@HackAfterDark Thank you!! I had to do some messing around, but I got some fantastic results!! Your help was wonderful, and they should show up soon if you wanted to see the results
@Vera97Â Happy I could help! They came out looking great! Thanks for sharing.
@HackAfterDark I'm a big fan of your lora here, it's so fun to play around with!
