LTX 2.3 INT8 MSR
Summary
Same-day LTX 2.3 multiple-subject reference workflow from javawock7618. This is the more practical LTX drop if you care about mixing several references into one scene instead of just doing plain text-to-video.

Developer notes
- The source README says this workflow can blend up to 5 inputs, including 1-4 subjects plus a background.
- The pack is built around distilled GGUF and INT8 paths for
lightricks/ltx-2.3. - The same pack also calls out an INT8 speedup path, prompt enhancement, and optional voice support in other graphs.
Our notes
- This is one of the more interesting LTX variants for consistency and scene control.
- On an RTX 3070 / 8 GB setup it is still tight, but it is a real workflow rather than a placeholder.
- Good pick when you want a reference-heavy LTX path instead of a generic one-shot generator.

Notes
- Best LTX import from this batch if you want reference blending and multi-subject handling.
- Expect to trim resolution and keep the graph lean on an 8 GB card.
