MiniMax H3高级配置·场景效果（Tlant）

The person moves, the camera moves, the world should move too. MiniMax H3高级配置·场景效果（Tlant） is the category that governs everything around and behind your subject - background preservation, scene expansion, background motion, lighting, atmosphere, hair and clothing physics, props, visual effects, and environmental events. It's the category that turns a "talking head over a static backdrop" into a scene with weather and life.

Same family architecture: it outputs a typed 场景效果配置 port that plugs into the Advanced Assembler's scene slot, and the assembler folds it into a stateless English instruction for a remote LLM. Leave it unconnected and the assembler fills it with seed-stable random values - a genuinely decent default for your first few tries, because H3 is good at grounding scenes from the source image.

The inputs worth knowing:

• 背景保持 - strict preserve, allow plausible expansion, limited local change, or complete theme-consistent reconstruction. Default 允许扩展 keeps the design while letting the camera move somewhere.
• 场景扩展 - whether the model may invent space beyond the frame during camera moves. 有限 (limited) is the sensible default; 禁止 if you want zero hallucinated geometry.
• 背景运动 - how much the background itself moves: none, subtle, moderate, strong. Subtle background motion is a cheap way to make a clip feel alive.
• 光线变化 - keep source lighting, a motivated light sweep, gradual brighten/darken, rhythmic pulses, color shifts, or theme inference. A gentle light change is one of the highest-value "cinematic" moves there is.
• 氛围元素 - the weather and air: breeze, rain, snow, fog, smoke/dust, floating particles, bokeh, lens flare. Theme inference is the safe default.
• 头发动态 and 服装动态 - hair and fabric motion, driven by action or wind. Auto works well; wind + hair is a classic attention-grabber when the subject allows it.
• 道具互动 - no props, interact only with visible existing props (the default), or allow one simple new prop. Keeps the LLM from materializing objects out of nowhere.
• 视觉特效 - none to high-energy effects. 轻微 (subtle) is usually the right amount for realism.
• 环境事件 - one background event for narrative interest: a practical-light change, curtains moving, people passing, a vehicle or moving light going by, an object shifting. It's the "give the background something to do" knob.

Output: 场景效果配置, a custom typed port that only connects to the assembler's scene slot. Chinese labels in, English prompt out.

The over-reach trap

The failure mode here is asking for everything at once - rain, fog, particles, lens flare, plus a full background rebuild in a 6-second clip. Effects compete for the same seconds and the result reads as a mess. Pick one hero element (the environment event, or the atmosphere, or the light change), keep 背景保持 conservative, and let the rest stay on their defaults. A single well-chosen environmental detail sells realism better than five stacked ones.
