- Attention to Detail
- Post-Processing and Presentation
Let’s take a closer look at each of them.
#1 Accuracy in Material Properties
- Diffuse Color and Texture: Use high-quality textures that accurately represent the material’s surface details, such as wood grain, concrete pores, or fabric weave.
- Specularity and Reflection: Define how a material interacts with light. Materials like glass, metals, or polished surfaces require accurate reflection and specular properties.
- Roughness/Glossiness: Control the sharpness or blurriness of reflections to represent whether a surface is smooth (e.g., polished marble) or rough (e.g., unfinished wood).
- Index of Refraction (IOR): For transparent materials like glass or water, ensure the IOR values are accurate to create realistic light behavior.
#2 Physical Correctness
Materials should behave as they would in the real world. Utilize Physically Based Rendering (PBR) workflows to ensure realism.
- Albedo: Avoid overly bright or saturated diffuse textures, keeping reflectance within physically plausible ranges.
- Normal/Displacement Maps: Add detail to the surface geometry without overloading the model’s polygons.
#3 Contextual Relevance
Choose materials that make sense in the context of the design, environment, and intended use of the space.

- HDRI Environments: Use HDRI maps to simulate real-world lighting and reflections.
- Light Interaction: Ensure metals have no diffuse component and rely solely on reflections, while non-metals (dielectrics) balance diffuse and specular reflection.
#6 Attention to Detail
Â
- Imperfections: Add subtle imperfections like scratches, smudges, or fingerprints to avoid “too perfect” materials.
- Weathering and Aging: Include wear and tear, such as patina on metal, faded paint, or chipped edges, to enhance realism.
- Variation: Introduce slight color or texture variations to prevent materials from looking flat or repetitive.
#7 Post-Processing and Presentation
Finalize materials through post-processing to harmonize them with the overall tone of the image.
- Color Grading: Adjust tones to match the scene’s atmosphere.
- Depth and Realism: Use ambient occlusion and subtle reflection passes to ground materials in the scene.
By adhering to these principles, you can create materials in arch viz images that enhance the design narrative and achieve a compelling level of realism.
