Research & Evidence-Based Practice Flashcards

Which online resource is most useful for researching accurate tiling and scale of architectural surface materials for 3D environments?

Answer: Architectural material databases such as Architextures or manufacturer technical specification sheets

Architectural material databases and manufacturer specs provide real-world dimensions and physical specifications for accurate material scaling in 3D scenes.

When building a substance graph for a material type you've never textured before, what should be your first research step?

Answer: Study the physical formation process of the material to understand its layered structure and surface characteristics

Understanding how a material physically forms—such as erosion, crystallization, or corrosion—informs the logical node structure of its procedural graph.

Which method best verifies that a researched texture's color values are perceptually accurate under different lighting conditions?

Answer: Validating albedo values using a waveform or histogram tool and testing under multiple HDRI lighting scenarios

Waveform tools and multi-HDRI testing validate that albedo values are not too dark or bright and behave correctly across lighting environments.

A studio requires textures for a product visualization of a new synthetic polymer. No physical samples exist yet. What is the best research strategy?

Answer: Research the polymer's chemical composition and reference materials with similar molecular structures and surface finish specifications from the manufacturer's data sheet

Manufacturer data sheets and chemical composition research provide the basis for accurate surface finish and optical property decisions when no physical sample exists.

Why is it important to research a material's index of refraction (IOR) when setting up specular highlights in a PBR workflow?

Answer: IOR is the physical basis for accurate specular intensity and directly corresponds to a material's real-world reflectivity

Index of refraction is the physical property that defines specular reflectivity, and using measured IOR values ensures physically accurate highlights for each material type.

When researching dirt and dust accumulation patterns for an environment asset, which principle from physics should guide placement?

Answer: Gravity and airflow cause dirt to collect on horizontal upward-facing surfaces and in crevices while vertical surfaces shed it

Gravity pulls particulates onto horizontal surfaces and into recesses, while vertical surfaces naturally shed accumulation—a physical reality that should drive texture research and placement.

Which research resource is most appropriate for validating roughness values for gemstones in a jewelry visualization project?

Answer: Gemological Institute of America (GIA) material specifications and optical property databases

Gemological databases provide precise optical measurements including surface finish and refractive properties needed for scientifically accurate jewelry rendering.
