sulphur_lora_rank_768.safetensors & Itx-2.3-22b-distilled-lora-1.1_fro90_ceil72_condsafe.safetensors “I’m not sure whether these two LoRA models should be used together or separately. What are the differences between them, and where should each one be applied? Could you please advise?” Thanks

I need an answer too. Need settings to reduce movement artifacts/ghosting coming from these. Do i use Ceil72 alongside the 384 Lora?

the sulphur_lora_rank_768 is amazing. I use it with a regular dev gguf ltx 2.3 along with the ltx 2.3 22b distilled lora 384 1.1. Then I added another lora node and load the the sulphur_lora_rank_768 . I added it like another regular lora. Works just fine for me. I set the lora model strength to about 0.8 to 1.0. By the way, I'm not an expert and I'm not sure if this is the correct way to use it. It just works in my case.

Hi. In my case, the custom LTX-2.3 I2V/T2V workflow I built (and shared on Civitai) is working wonders with the combination of Distilled GGUF(unsloth LTX-2.3-GGUF) + VBVR LoRA + sulphur_lora_rank_768 LoRA. It delivers excellent results even for... well, 'certain' types of content, if you know what I mean. It’s performing absolutely brilliantly.

Notes and Additions)

Models that require ltx-2.3-22b-distilled-lora-1.1_fro90_ceil72_condsafe LoRA:

sulphur_dev_bf16.safetensors
sulphur_dev_fp8mixed.safetensors

Models that do NOT require ltx-2.3-22b-distilled-lora-1.1_fro90_ceil72_condsafe LoRA:

sulphur_distil_bf16.safetensors

When to use sulphur_lora_rank_768.safetensors:

This is required for standard LTX-2.3 models.

This is my current understanding.
