The creator of this LoRA is Playtime-AI. Since I'm really impressed with it and Playtime-AI hasn't uploaded it to Civitai yet, I'd like to support their outstanding work by sharing this LoRA with you all. So far, I've only tested it for "Image-to-Video," but it works perfectly.

I combine the "Breasts Drop LoRA" with K3NK's "M4CROM4STI4 – Huge Natural Breasts – LTX2.3 – K3NK." The results are outstanding, and you can easily control the breast size. Here’s an example:

"[TECHNICAL LTX 2.3 SETTINGS] motion_strength: 68 | seed: [INSERT_SEED] | duration: 15s | fps: 24 | style: semi-realistic/cinematic/daylight | consistent_anatomy: true | dynamic_scale_big massive_breasts: +15.0x (large/gigantic breasts: 15.0) | soft_tissue_physics: ultra-high | gravity_weight: extreme | lap_contact: enabled | audio_sync: ambient_outdoor_0:00, dialogue_sigh_0:08, fabric_rustle_black_top_0:05 + shirt_slide_0:06 | lip_sync: enabled | voice_accent: Relaxed/Soft | M4CROM4STI4 | large pendulous breasts".

🛠 Recommended Setup & Workflow: To get the best results, make sure you're using the latest base checkpoint ltx-2.3-22b-distilled-lora-384-1.1:

⚠️ Please download version 1.1 specifically, as it's required for full compatibility.

I'm running this LoRA in a slightly older DaSiWa LTX2.3 workflow that I've optimized over time. It just needed a few minor tweaks, but it runs very reliably now:

For the text encoder, I recommend either: • gemma-3-12-it-heretic-V2_fp8_e4m3fn: https://huggingface.co/DreamFast/gemma-3-12b-it-heretic-v2
• gemma312bQatAbliterated_gemma312BNVFP4HF: https://civarchive.com/models/2461299/gemma-3-12b-qat-abliterated-sikaworld-fp4-ltx2?modelVersionId=2767671
Both work perfectly with this LoRA.

🖥️ Checkpoint & Hardware:

For inference, I use ltx2310eros_v1 bf16 (the full 42.97GB model). I haven't tested the smaller variant yet, but on an RTX 5090 it runs exceptionally well, especially for "Image-to-Video".

Have fun creating! 🚀
