  1. What does PBR stand for in modern 3D texturing workflows?

    Answer: Physically Based Rendering

    PBR stands for Physically Based Rendering, a shading approach that simulates how light interacts with surfaces in the real world.

  2. In a PBR workflow, what does a Metalness map define?

    Answer: Which parts of a surface are metallic versus non-metallic

    A Metalness map uses black-and-white values to distinguish metal (white) from non-metal (black) areas on a surface.

  3. What is the primary purpose of a Normal map in 3D texturing?

    Answer: Simulate fine surface detail without adding geometry

    Normal maps encode surface direction data to fake small bumps and details by altering how light hits the surface.

  4. What does a Roughness map control in a PBR shader?

    Answer: How sharp or blurry reflections appear on a surface

    The Roughness map controls micro-surface irregularity, where white = rough (blurry reflections) and black = smooth (sharp reflections).

  5. What is UV unwrapping in 3D modeling?

    Answer: Flattening a 3D mesh's surface into a 2D coordinate space for texture mapping

    UV unwrapping unfolds a 3D mesh into a flat 2D layout (UV space) so 2D textures can be applied correctly to the surface.

  6. What does an Ambient Occlusion (AO) map represent?

    Answer: Areas where ambient light is occluded or blocked by nearby geometry

    An AO map stores soft shadows in crevices and corners where ambient light is less likely to reach, adding depth to surfaces.
