终结"3D渲染成2D"观感的诀窍：一个风格锚点。一张平面赛璐珞定稿帧，整支视频的渲染都从中继承。

the trick that killed the "3D rendered as 2D" look: a style anchor. one flat-cel frame the whole video inherits its rendering from. Seedance V2 prompt 👇 [SHOTLINE PROMPT — THE FALLEN KEEP, marked / chart-mapped version] [STYLE] Hand-drawn 2D cel animation, authentic 1990s TV/OVA production look. · Coloring: flat uniform color fills, exactly ONE hard-edged shadow tone. NO gradients, no soft light, no volumetric light, no ambient occlusion, no glossy highlights. · Line: visible pencil-derived outlines, line weight breathing with the motion, drawn outlines (not model edge-detection). · Background: hand-painted watercolor/poster-paint art board as a SEPARATE material layer from the cel characters, moving in flat parallax planes (near/mid/far). No real 3D spatial travel. · Motion: traditional "on twos" (12 drawings per second feel), slight keyframe-to-keyframe jump. NO 60fps smooth interpolation. · Grain: low-saturation film grain, faint VHS softness, like a scanned cel. STRICTLY FORBIDDEN: 3D render, CG, cel-shaded 3D, game-engine look, realistic material lighting, real depth-of-field blur, plastic surfaces, ray-traced reflections. Continuous one-shot lateral tracking, real-time pacing. NO chart graphics on screen: no glowing path line, no numbers, no labels, no minimap, no timeline, no subtitles, no UI. [REFS] @ image1 = the one-shot blocking chart (THE FALLEN KEEP). Use it ONLY for scene layout and the position of nodes 1-7. Ignore its rendering and all overlay graphics. @ image2 = style anchor (a 90s cel key frame). ALL rendering, coloring (flat + one shadow tone), linework, painted-background material and grain follow this frame as the single source of truth. Character: young swordswoman, short dark bob, long red scarf, light plate over travel clothes. ⚠️ Only ONE protagonist on screen at any moment. The chart repeats her at 7 spots; that is chart language, not the video. No clones, no duplicates. ⚠️ Weapon logic: she starts empty-handed. A guard throws her a sword at 00:03. After the catch the sword stays in hand and never disappears. ⚠️ Scarf never disappears. She always runs left to right, never doubles back. Every background soldier looks different, no copies. ━━ SEGMENT A | 0:00-0:15 (nodes 1-4) ━━ [00:00-00:03] 📍 NODE 1, the shattered gate (far left). Empty-handed, she bursts through the broken gate into the corridor, splinters and sparks flying, ruined depth behind her. CAM: establishing lateral start, show the corridor's scale. [00:03-00:06] 📍 NODE 2, the guard by the wall. Mid-run she catches a sword a dying guard throws, exchanges a glance, keeps going. CAM: lateral follow, full body. First appearance of the weapon. [00:06-00:10.5] 📍 NODE 3, the collapsed pillar. She vaults the pillar full-body, scarf arcing, lands into a roll and back into the sprint. CAM: continuous tracking with a slight dip, NO cut across these 4.5s. [00:10.5-00:15] 📍 NODE 4, the burning tapestry wall. She shields her face from the heat, flames flickering on the flat cel shadows, ash drifting. End frame: still at the burning wall, running, head turning toward the wall. CAM: continuous lateral tracking, flame flicker on her face. ━━ SEGMENT B | 0:00-0:15 (nodes 5-7, continues from Segment A's end frame) ━━ [00:00-00:03] 📍 NODE 5, a wounded soldier by the wall. She skids to a stop, kneels, presses his hand onto his wound, holds his eyes a beat, rises. CAM: brief hold, mid shot. The one quiet beat. [00:03-00:07] 📍 NODE 6, the falling chandelier. As she steps off, an iron chandelier crashes half a step behind her, sparks and rolling rings, the blast lifting her scarf. She does not look back. CAM: pull wide to hold the whole fall, NO cut across these 4s, camera shakes on impact. [00:07-00:11.5] 📍 NODE 7 (approach + door), the war-room door. She sprints the last stretch and side-kicks the heavy door open, splinters flying, moonlight pouring in. CAM: push-in, slight forward lunge as she passes through. [00:11.5-00:15] 📍 NODE 7 (stairs), the moonlit rampart. She climbs the stone stairs, moon and distant firelight (flat cool color shapes) falling on her, and on the top step holds her blade across her body, blade catching a flash of moonlight. End on her blade-drawn silhouette. CAM: rise with the stairs, settle to mid shot, no wide pull-out. [AUDIO] no music, no subtitles. SFX only: gate crash and sparks, distant siege rumble, sword whoosh and metal ring on the catch, footfalls and armor, vault and roll, roaring fire and drifting ash, skid and the wounded soldier's groan, chain snap and chandelier crash with bouncing rings, side-kick and splintering door, stair steps settling, night wind, a single ringing note as the blade holds. [Run in two 15s Seedance 2.0 segments, B extended from A's final frame. Both segments load @ image1 (chart) + @ image2 (style anchor).]
