# How do you "AI-render" a 3D layout locally (3D passes -> video model), and how did the best local approach change from Feb to Aug 2026?

Three Mickmumpitz videos trace one pipeline across 2026. Feb (V1): Inner-Reflections' VACE + SkyReels V3 R2V merge (Apache-2.0 card) reads control passes (VACE) and reference images (SkyReels); export an outline pass (Blender Workbench flat black + white outlines, or Freestyle as a render pass) and a normalized/inverted Z depth pass with a contrast curve; outlines keep composition but let the model invent detail, depth follows geometry more tightly, blend both if needed; keep control-net strength low for start-frame image generation (Z-Image Turbo + control nets); free workflow ~120 frames at 24 fps; paid version chains 81-frame chunks with 11 overlapping start frames for long shots. Jun (V2, NVIDIA-sponsored): rebuilt on LTX 2.3 (audio+video model) with NVIDIA's blueprints (Blender text-to-assets via Llama 3.1 + TRELLIS; FLUX-depth keyframes inside Blender); merged depth+Canny control video; a black mouth/face mask frees that region so injected dialogue audio drives lip sync/facial animation (without the mask the control passes suppress mouth motion); guide frames placeable at any frame with strength (0.75 used); resolution divisible by 64; on RTX 5090 a 330-frame shot rendered in ~1m50s (NVFP4/FP8 + distilled LoRA); RTX Video Super Resolution to 4K. Aug (V3): MiniMax H3 needs only a clay playblast plus optional image/audio references (no control-net extraction); clip length must match allowed values at 24 fps; 8 steps with speed LoRA + EasyCache vs 20 steps for quality; pruned ~12 GB variant for older GPUs; generates foley/music and lip sync from an audio file. Recurring failure: camera sliding when the layout lacks texture (white backdrop) - add a floor grid or blockout detail; extreme camera moves still break; lip sync degrades when the character is far from camera.

Curator qualifications: Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. Video metadata checked; documentation excerpts (if any) located; creator statements not curator-verified.

Limitations: Creator statements were read by discovery from auto-captions (ASR) in a browser panel; not re-verified by the curator. V2 is NVIDIA-sponsored with supplied hardware; timings are not comparable across videos. LTX-2.3 and H3 are community licences (custom terms not read). ASR: "Kenny"=Canny, "defaf"=dev.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
