  1. What is the purpose of a 'cavity map' when texturing a 3D model?

    Answer: Highlighting crevices and indentations to add dirt or detail

    A cavity map captures recessed areas of a surface, commonly used to add accumulated dirt, grime, or shadow detail in those grooves.

  2. In Mari (Foundry), what makes it better suited for film-quality character texturing than Substance Painter?

    Answer: It natively supports UDIM workflows and very high-resolution painting across multiple tiles

    Mari was built specifically for film-quality asset texturing with full UDIM support, allowing artists to paint across dozens of high-resolution tiles simultaneously.

  3. What does 'mip mapping' accomplish in real-time 3D rendering?

    Answer: Pre-generates downscaled versions of a texture used at different distances to reduce aliasing

    Mip maps are pre-computed sequences of lower-resolution texture versions that the GPU samples when an object is far away, reducing shimmering and improving performance.

  4. Which node in Substance Designer generates a grayscale map showing which areas of a surface face upward versus downward?

    Answer: World Space Normal node

    The World Space Normal node converts tangent-space normals to world space, enabling gradient masks based on surface orientation (top-facing, side-facing, etc.).

  5. What is the primary advantage of using 'smart materials' in Substance Painter?

    Answer: They apply multiple texture layers with masks already set up based on mesh curvature and AO

    Smart materials in Substance Painter include pre-configured layer stacks with procedural masks driven by baked mesh data like curvature and ambient occlusion.

  6. In a PBR metalness workflow, what value should the metallic map have for a purely dielectric (non-metal) surface?

    Answer: 0.0 (black)

    In the metalness workflow, 0 (black) indicates a non-metal (dielectric) and 1 (white) indicates a pure metal — no in-between values should be used for physically accurate results.

  7. Which DCC application is primarily used for UV unwrapping and is known for its 'Unfold3D' algorithm?

    Answer: RizomUV

    RizomUV (formerly known as Unfold3D) is a dedicated UV unwrapping tool that uses the Unfold3D algorithm to minimize distortion in UV layouts.
