Large File Sizes Due to PBR Material Usage in SketchUp 2025

  • 1.  Large File Sizes Due to PBR Material Usage in SketchUp 2025

    Posted 06-25-2025 07:44

    Since the implementation of Physically Based Rendering (PBR) materials in SketchUp 2025, this version has introduced a new graphics system for materials. This system enables PBR materials to react dynamically to light and the model's environment, resulting in enhanced visual realism. However, this improvement leads to a significant increase in file sizes, which can impede cloud management, particularly for complex projects.

    Below is a comparative study of file sizes between SketchUp 2025 and previous versions (2018-2024) that did not utilize PBR materials:

    SketchUp 2025:

    • Ej. 1: Model with a 2x2x2 cube and solid white color, 12 edges, 6 faces, 1 component, 1 material → 0.03 MB

    • Ej. 2: Model with a 2x2x2 cube and "Brick" PBR material, 12 edges, 6 faces, 1 component, 1 material → 5 MB

    • Ej. 3: Model with four 2x2x2 cubes and different PBR materials, 48 edges, 24 faces, 1 component, 4 materials → 11.7 MB

    • Ej. 4: Model with four 2x2x2 cubes and different PBR materials, 48 edges, 24 faces, 1 component, 4 materials, 1 environment → 18.4 MB

    SketchUp (2018-2024):

    • Ej. 1: Model with a 2x2x2 cube and solid white color, 12 edges, 6 faces, 1 component, 1 material → 0.03 MB

    • Ej. 2: Model with a 2x2x2 cube and "Brick" material, 12 edges, 6 faces, 1 component, 1 material → 0.18 MB

    • Ej. 3: Model with four 2x2x2 cubes and different materials, 48 edges, 24 faces, 1 component, 4 materials → 0.21 MB
