# Glassify UI > Transform a UI screenshot into a structured Cinema4D/Octane JSON render prompt for photorealistic 3D poster art. Use this skill whenever the user uploads a UI screenshot (app, website, tool, dashboard) and wants a Cinema4D render prompt, 3D poster, AIGC image prompt, or any photorealistic visualization of an interface. The output is always a clean JSON file — never prose or Midjourney text strings. - Skill: `magiccube/glassify-ui` (Agent Skill) - Install (CLI): `npx skillmds@latest add magiccube/glassify-ui` - Raw SKILL.md: https://api.skillmd.com/api/skills/magiccube/glassify-ui/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Design & Media - Author: magiccube (https://skillmd.com/u/magiccube) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/magiccube/glassify-ui --- # Cinema4D UI Render Skill Transform a UI screenshot into a structured JSON render prompt for Cinema4D/Octane. Output purpose: **promotional poster art**, not documentation. Abstraction beats fidelity. --- ## Core Philosophy: "舍得" (Less is More) A poster is not a screenshot. The JSON you produce must: - **Simplify layers** — 4–8 layers max. Merge minor UI regions. Omit decorative chrome. - **Abstract content** — No literal button labels unless they define the product identity. Use semantic descriptions: `"primary action buttons row"` not `"Bold / Italic / Underline"`. - **Elevate the hero** — One layer is the visual anchor (the "hero slab"). Give it the prominent glow, active color, and bloom effect. Everything else supports it. - **No clutter** — Status bars, scrollbars, tooltips, and minor icons: omit entirely unless they are distinctive brand elements. - **Extract interactive controls as micro_elements** — Every visible button, toggle switch, pill chip, or CTA must be listed in the `micro_elements` array as an independent glass brick with its own z_offset, shape, and tint. Do NOT bury them inside a parent layer's `content` description. This is mandatory — missing micro_elements is a critical error. --- ## Step 1 — Analyze the Screenshot Look at the screenshot and extract: 1. **UI category**: productivity / developer / creative / mobile / web / dashboard 2. **Brand identity signals**: dominant color, logo, product name, characteristic icon 3. **Natural focal region**: which area draws the eye first — that becomes the hero layer 4. **Aspect ratio decision** (if user has not specified): - Desktop/web UI with wide layout → `"16:9"` - Mobile app or portrait-first UI → `"9:16"` - Square or ambiguous → `"1:1"` or `"16:9"` as default --- ## Step 2 — Design the Layer Stack Collapse the real UI into **4–8 abstract depth layers**, Z-offset spaced 5–6mm apart. Use this table as a starting template — adapt to the actual UI: | Layer ID | Typical Role | Z offset | Thickness | Roughness | Transmission | |----------|------------------------|----------|-----------|-----------|--------------| | 0 | App shell / chrome | 0mm | 8mm | 0.20 | 0.50 | | 1 | Background / canvas | 5mm | 6mm | 0.15 | 0.65 | | 2 | Main content area | 10mm | 5mm | 0.06 | 0.85 | | 3 | Primary toolbar/nav | 15mm | 5mm | 0.12 | 0.70 | | 4 | Hero element | 20mm | 4mm | 0.08 | 0.75 | | 5 | Floating accent (opt.) | 25mm | 3mm | 0.18 | 0.60 | Rules: - The **hero layer** gets `glow` and `active_element` with `effect: "backlit_halo_bloom"` - Content descriptions use **semantic phrases**, never exhaustive lists of UI elements - Omit Layer 5 if the UI has no natural floating element ### micro_elements (mandatory if interactive controls exist) After the main layer stack, scan the screenshot for every interactive widget: buttons, toggle switches, pill chips, dropdown triggers, submit CTAs, radio buttons, sliders. Each one becomes an entry in `micro_elements` — a separate floating glass brick: ```json "micro_elements": [ { "id": "me_01", "type": "toggle_switch", "label_semantic": "Computer mode toggle — active state", "parent_layer_id": 1, "z_offset_mm": 28, "shape": "pill", "size": "small", "material": { "thickness_mm": 2.5, "roughness": 0.05, "transmission": 0.80, "tint": "accent_blue" }, "glow": { "color": "#4AA8FF", "intensity": 0.5, "radius_mm": 6, "effect": "edge_rim_glow" } } ] ``` `type` values: `button_primary`, `button_secondary`, `toggle_switch`, `pill_chip`, `dropdown_trigger`, `icon_button`, `cta_submit`. `shape` values: `rectangle`, `pill`, `circle`, `square`. `tint` values: `accent_blue`, `accent_teal`, `neutral_white`, `clear`, `warm_white`, `cool_white`. --- ## Step 3 — Choose Environment & Tone Default white balance is **neutral-to-slightly-cool** (5200–5600K). Avoid warm golden tones unless explicitly requested. Match environment to UI category: | UI Category | Environment | Tone | Palette | |------------------|-----------------------------------|--------------|-----------------------| | Productivity | bright_minimal_desk_daylight | neutral_cool | clean_daylight | | Developer / Code | dark_minimalist_desk_led_strip | cool | cool_white_led | | Creative / Design| architects_drafting_table | neutral_cool | soft_overcast | | Mobile App | white_marble_surface_lifestyle | neutral_cool | clean_daylight | | Dashboard / Data | glass_conference_table | cool | morning_cool_light | Props are 2–3 contextually appropriate objects, soft bokeh background. UI float height: 15–20cm above surface. --- ## Step 4 — Output the JSON Produce exactly this structure. No extra fields, no prose, no markdown around the JSON. ```json { "task": "photorealistic_3d_render", "renderer": "Cinema4D_Octane", "resolution": "8K", "aspect_ratio": "<16:9 | 9:16 | 1:1>", "source_ui": "", "negative_prompt": [ "no annotation text", "no dimension labels", "no callout lines", "no layer name overlays", "no technical labels in scene", "no dark mode UI", "no dark backgrounds on UI panels", "no `Layer 1`, `Layer 2`, ..., `Layer N` callouts and annotations" ], "layers": [ { "id": 0, "name": "", "z_offset_mm": 0, "content": [""], "material": { "thickness_mm": 8, "roughness": 0.20, "transmission": 0.50, "tint": "" }, "glow": null } ], "micro_elements": [ { "id": "me_01", "type": "", "label_semantic": "", "parent_layer_id": 1, "z_offset_mm": 28, "shape": "", "size": "", "material": { "thickness_mm": 2.5, "roughness": 0.05, "transmission": 0.80, "tint": "" }, "glow": null } ], "hero_layer_id": "", "material_global": { "type": "frosted_acrylic_glass", "edge_bevel_mm": 1.5, "chromatic_aberration": true, "ray_traced_reflections": true, "ambient_occlusion_between_layers": true }, "environment": { "scene": "", "surface": "", "props": ["", ""], "ui_float_height_cm": 18, "caustic_shadow_on_desk": true }, "camera": { "angle": "three_quarter_perspective", "tilt_degrees": 10, "position": "slightly_right_of_center", "focal_length_mm": 100, "aperture": "f/1.2", "bokeh_blur": true, "focus_target": "layer_", "dof_blur_layers": [0, 1, "environment"] }, "lighting": { "tone": "neutral_cool", "white_balance_kelvin": 5400, "palette": "", "key": { "position": "top_center", "color": "#F5F8FF", "type": "soft_area" }, "rim": { "position": "upper_left", "color": "#C8DEFF", "type": "backlit_edge" }, "fill": { "position": "lower_right", "color": "#EAF0FF", "type": "bounce" } }, "style_tags": [ "photorealistic", "Fluent_Design", "physically_based", "light_mode_ui", "neutral_cool_white_balance", "no_annotation_text", "no_cartoon", "no_flat", "no_watermark" ] } ``` --- ## Quality Checklist (self-review before output) Before writing the final JSON, verify: - [ ] Layer count is 4–8, not more - [ ] Each `content` array has ≤ 3 items, all semantic (no literal button labels) - [ ] Exactly one layer has a `glow` value and an `active_element` - [ ] `hero_layer_id` matches that layer's `id` - [ ] `focus_target` in camera matches `hero_layer_id` - [ ] Environment and tone are consistent — default is **neutral_cool**, never warm/golden unless user asked - [ ] `white_balance_kelvin` is set (5200–5600K range for neutral cool) - [ ] `negative_prompt` array is present and includes annotation-text suppressors - [ ] `micro_elements` array is present if the UI has any buttons, toggles, or chips - [ ] Every button / toggle / pill in the screenshot has a corresponding `micro_element` entry - [ ] `style_tags` includes `"light_mode_ui"` and `"no_annotation_text"` - [ ] Aspect ratio is decided and justified - [ ] No `midjourney_suffix` or prose fields present
