AGGA's Utopia —「illustrious-SDXL」Qimera V3

📦 AGGA’s UtopiaXL v3Q – The Chimera Update 🧬

Sorry for the confusion, but it's fixed now!

Honestly, I didn’t expect it to have the same hash. When I tested it a few days ago, it looked different (though I may have confused it with the Q-A1 version, which included more Pony data and ended up being discarded~).

⚙️ What is UtopiaV3Q?

This is not a traditional update.

UtopiaV3Q is a parallel refined version, designed to improve compatibility with LoRAs from the following ecosystems:

✅PonyDiffusion

✅Illustrious 0.1 / 1.0 / 2.0

✅SDXL 1.0

✅Noob-AI

…without compromising the core visual identity of the model.

To achieve this, carefully selected LoRA extracts were fused using a low total alpha of 0.25. This was just enough to synchronize the internal architecture with the activation patterns expected by those environments — without significantly altering the style or tone of Utopia.

🧠 What changed?

The original V3 version had issues with LoRAs trained on Illustrious 0.1, which only worked properly with very low weights (~0.5).

Now, in V3Q, those same LoRAs can be used comfortably with weights up to 0.8+, without distortion or degradation.

🐎 Bonus:

The model now also recognizes tags and triggers from PonyDiffusion, allowing character and concept LoRAs from that ecosystem to function properly. Visually, not much has changed — but conceptually, the model understands a lot more.

In short:

UtopiaV3Q is a refined chimera, made not to overwrite the style, but to understand more LoRA dialects.

⚙️ Optimal Settings Guide (Same as v3.0)

🧭 Steps: 14–28 (Sweet spot: 20–24)

🎯 CFG Scale: 4.5 for soft style, 5.5+ for crisp details

📈 Samplers: DPM++ 2M Karras, Euler a, DPM++ SDE

🖼️ Resolution: 1024×1024 and up – 1152×1344, 1536×896 work well

🔁 Upscalers: R-ESRGAN 4x+ Anime6B / 4x-UltraSharp

🧠 Prompting Tips

Positive:

(masterpiece), (best quality), ultra-detailed, greatscore, score9, anime style, cute, absurdres, detailed lighting, shiny skin, cinematic, dynamic pose

Negative:

bad anatomy, worst quality, extra limbs, sketch, watermark, signature, cropped, shiny skin (if unwanted), lowres, blurry, oil skin, artist name

🧪 Fun fact:

You can now combine NoobAI-style LoRAs with Pony-style and even standard SDXL LoRAs in a single generation. It shouldn’t glitch unless weights are too extreme — play around with alpha 0.4–0.7 for safest results.
