Pushing LTX 2.3 I2V: Moving gears, leg pistons, and glossy porcelain reflections (ComfyUI / RTX 4090)

Hey everyone. I've been testing out the LTX 2.3 (ltx-2.3-22b-de) Image-to-Video built-in workflow in ComfyUI. My main goal this time was to see if the model could handle rigid, clockwork mechanics and high-gloss textures without the geometry melting into a chaotic mess. For the base images, I used FLUX1-de paired with a custom LoRA stack, then fed them into LTX 2.3. The video I uploaded consists of six different 5-second scenes. The Setup: CPU: AMD Ryzen 9 9950X GPU: NVIDIA GeForce RTX 4090 (24GB VRAM) RAM: 64GB DDR5 Target: Native 1088x1920 vertical.
