What does PBR stand for in 3D product material creation?
Answer: Physically Based Rendering
PBR (Physically Based Rendering) is a shading approach that simulates how light interacts with real-world materials using physically accurate algorithms.
In PBR workflows for product animation, what does the 'metallic' map control?
Answer: Whether a surface is treated as a metal or dielectric (non-metal) for light interaction
The metallic map is a black-and-white mask where white designates metallic surfaces (reflective with tinted highlights) and black designates dielectric surfaces.
What is the purpose of a normal map in product texturing?
Answer: To simulate fine surface detail and micro-bumps without adding geometry
Normal maps store surface direction data in RGB channels to fake the appearance of raised or recessed detail on a low-polygon product mesh.
What does UV mapping refer to in 3D product modeling and texturing?
Answer: The process of unfolding a 3D surface into a 2D layout so textures can be applied correctly
UV mapping unfolds the 3D mesh into a flat 2D space so bitmap textures can be precisely placed and aligned on the product surface.
What material type is used in 3D product animation to simulate glass bottles or transparent packaging?
Answer: Principled BSDF with low roughness and high transmission
Glass is simulated using a transmission-based BSDF (bidirectional scattering distribution function) with near-zero roughness to achieve a realistic transparent appearance.
In product animation, what is the role of an ambient occlusion (AO) map?
Answer: To darken crevices and contact areas where light is naturally occluded, adding depth and realism
AO maps simulate the soft shadow that accumulates in corners, grooves, and tight spaces where light is blocked, enhancing the perceived depth of product detail.
