Developer notes

• Comes from the same-day javawock7618 LTX 2.3 workflow pack.
• The pack describes this as the Multiple Subject Reference path, with up to five input references.
• INT8 is the main reason to keep this one around instead of treating it as a novelty pack.

Our notes

• This is the strongest new LTX import for character, object, and multi-reference consistency.
• It is probably still heavy on an RTX 3070 / 8 GB, but the INT8 path makes it the most practical version of this idea to keep testing.
• Good candidate for later comparison against the repo's simpler LTX character-sheet workflows.

Required custom nodes

• ComfyUI-KJNodes
• ComfyUI-LTXVideo
• keyframeflf / flf helpers used by the pack

Required models

• lightricks/ltx-2.3 distilled GGUF or INT8 weights, depending on the local setup

Notes

• Best same-day LTX workflow for reference and subject-composition work.
