### Step-by-Step Material Setup Guide
#### 1. Bedding & Pillows (Soft Fabric / Cotton / Linen)
* **Shader:** Assign an `aiStandardSurface`.
* **Base Color:** Connect a diffuse/albedo fabric texture or set a warm neutral off-white/beige tone.
* **Roughness:** Set between **0.65 – 0.85**. Fabric scatters light evenly and should not look shiny.
* **Sheen (Crucial for Fabric):**
* **Weight:** Set to **0.4 – 0.7**.
* **Roughness:** Keep around **0.3 – 0.5**.
* *Why:* Sheen simulates micro-fibers along the glancing angles of the cloth (velvet/cotton falloff).
* **Bump / Normal Mapping:** Plug a woven fabric normal map into the **Geometry - Bump Mapping** slot (`Tangent Space Normals`). Ensure the normal map node's **Color Space** is set to **Raw**.
---
#### 2. Wooden Furniture (Nightstand, Bedframe & Chair)
* **Shader:** Assign an `aiStandardSurface`.
* **Base Color:** Connect an albedo wood texture map (Color Space: `sRGB`).
* **Roughness:** Connect a grayscale roughness map (Color Space: `Raw`) into **Specular - Roughness**.
* Typical scalar value if not using a map: **0.35 – 0.5**.
* **Specular IOR:** Default **1.5** works well for varnished wood.
* **Normal / Bump:** Connect a fine wood-grain normal map (Color Space: `Raw`) with a subtle bump depth (around `0.02 – 0.05`).
---
#### 3. Cast Iron Radiator (Painted or Matte Metal)
* **Option A: Painted Enamel (Common for vintage radiators)**
* **Base Color:** Off-white or light warm grey.
* **Roughness:** **0.35 – 0.45** (semi-gloss finish).
* **Metalness:** **0.0** (paint behaves as a dielectric layer).
* **Bump:** Add an `aiNoise` node to the bump slot with very small amplitude to simulate uneven cast iron texture under the paint.
* **Option B: Raw / Aged Cast Iron**
* **Base Color:** Dark charcoal/grey.
* **Metalness:** **0.8 – 1.0**.
* **Roughness:** **0.6 – 0.75**.
---
#### 4. Interior Plaster Walls
* **Shader:** Assign an `aiStandardSurface`.
* **Base Color:** Warm white / light cream.
* **Roughness:** Set high, around **0.8 – 0.95**.
* **Bump Mapping:** Create a subtle micro-texture using an Arnold `aiNoise` node connected to the Bump slot:
* Bump value: very low (around `0.005 – 0.01`).
* Noise scale: high frequency so it breaks up flat digital highlights.
---
#### 5. Window Glass
* **Shader:** Assign an `aiStandardSurface`.
* **Base Weight:** **0.0**.
* **Specular Weight:** **1.0** with **Roughness = 0.0** and **IOR = 1.52**.
* **Transmission Weight:** **1.0** (pure white).
* **Arnold Object Settings:**
* Select the window glass mesh.
* In the **Attribute Editor**, open the **Arnold** dropdown.
* **Uncheck "Opaque"** (if left checked, shadows behind the glass will render completely black).
---
#### 6. Glass Bottle on the Nightstand
* **Shader:** Assign an `aiStandardSurface`.
* **Base Weight:** **0.0**.
* **Transmission Weight:** **1.0**.
* For amber/brown beer glass: Set **Transmission - Color** to an amber/brown hue, or set **Scatter / Transmittance** depth.
* **Roughness:** **0.05 – 0.1** (a tiny amount keeps it from looking CG-perfect).
* **Arnold Mesh Setting:** Ensure **Opaque is unchecked** in the shape node.
---
### Core Arnold Settings & Workflow Tips
1. **Color Management (ACES / OCIO or SynColor):**
* Albedo/Color textures: Set **Color Space** to **sRGB**.
* Utility textures (Roughness, Metallic, Bump, Normal, Displacement): Always set **Color Space** to **Raw**, and check **Alpha is Luminance** under the File node's *Color Balance* tab.
2. **Diffuse Roughness for Walls/Plaster:**
* In `aiStandardSurface - Base`, increasing **Diffuse Roughness** (Oren-Nayar model) to **0.3 – 0.5** produces a powdery, flat look ideal for dry drywall and plaster.
3. **Lighting Interaction:**
* Because your scene is named `Sunrise3.mb`, ensure your `aiSkyDomeLight` uses an HDRI with a warm, low-angle sun, or supplement it with an `aiAreaLight` or `aiDirectionalLight` pointed through the window frame to cast distinct morning window shadows onto the wall.
