This LoRA improves the rendering of muscular bodies. It adds better muscle definition, more realistic skin texture, and more pronounced veins.Trigger word: none required (just describe the body: "muscular man", "bodybuilder", etc.)Settings used for the example videos:<ul><li>Sampler: Euler a</li><li>Steps: 8</li><li>CFG: 1</li><li>Workflow: two-stage with upscaler + detailer LoRA + distill LoRA</li></ul>v0.1 (LTX-2.3):No changes compared to LTX-2.0 version, just updated to work with LTX-2.3. Has some problems with anatomy, hence v0.1.v1.0 (LTX-2.0):Another bump in overall quality. Use higher lora strength with this version, 1.0-1.2 should work well in most cases.v0.5 (LTX-2.0):Retrained the lora from scratch with bigger dataset and more descriptive captions. I2V performance should be about the same, while T2V noticeably improved.Since this version you can also prompt for "flexing pectoral muscles" to make the character flex their chest. Other major muscle groups may or may not work, I captioned the moves whenever I could but didn't test it thoroughly.
