品牌浮雕Logo金属化材质渲染

{argument name="品牌名称" default="LUXORA"} + {argument name="金属色调" default="玫瑰金"}
Act as a Senior CGI Artist and Brand Identity Director specializing in premium logo materializations. Your reference aesthetic: a logo mark that appears to have been pushed outward from behind a {argument name="表面材质" default="拉丝金属"} surface — like a relief stamp pressed from the reverse side of a metal sheet, a hallmark embossed on luxury packaging, or a raised seal on official documents. The logo does not exist as a separate standing object placed on a surface. It exists as a raised relief, an outward protrusion that is part of the surface itself.

BRAND INTELLIGENCE SYSTEM
Before executing any phase, resolve these parameters:
(1) LOGO GEOMETRY — identify {品牌名称}'s primary icon mark in its simplest most reduced form — the mark that works at any scale.
(2) COLOR PALETTE — based on {金属色调}, build the full tonal system from the lightest specular highlight to the deepest shadow tone.
(3) SURFACE MATERIAL — based on {金属色调}: silver/grey → brushed or circular-grain steel; gold/champagne → warm brushed metal with radial grain; black → anodized aluminum or matte carbon fiber; white → matte ceramic or chalk plaster; saturated hue → anodized colored metal.
(4) LIGHT DIRECTION — determine the most flattering single light angle to reveal the emboss topography.

PHASE 1: SURFACE & ATMOSPHERE
The entire image is one single continuous material surface — not a background with an object placed on it, but one unified physical plane filling the entire canvas. This surface is made of the SURFACE MATERIAL resolved above. The surface has a subtle radial gradient in its lighting — brighter near the center where the embossed logo sits, gradually darkening toward all four edges. Apply fine uniform grain texture across the entire surface at ISO 800 equivalent.

PHASE 2: THE EMBOSS — CRITICAL
The {品牌名称} logo mark is rendered as a full bas-relief — think of a coin, a commemorative medal, or a luxury brand stamp. The ENTIRE logo shape rises as one unified solid mass from the surface — every filled area, every curve, every solid region pushes outward as one piece, at a uniform height above the surrounding flat surface. The top face of this raised form is slightly convex — gently domed — so it catches the key light across its full width. The transition from flat surface to raised form follows a smooth beveled wall — curved, not sharp — like the edge of a coin. Negative spaces WITHIN the logo are recessed back to the flat surface level, creating clean negative voids.

PHASE 3: LIGHTING & FINISH
One primary soft area light from {argument name="光源方位" default="左上10-11点钟"} — broad and diffused, wrapping around the curved walls to create highlight peak at the top and gradual shadow descent on the far wall. {argument name="后期处理" default="微妙电影级颗粒感, 微光反射, 无文字, 无水印"}
