Transmutr alternatives compared
Compare Transmutr with Skimp, Universal Importer, Decimify, FluidImporter, and SimLab. Feature matrix, published 1 million face import times, and 5-star simplification quality ratings.
Feature comparison
| Feature | Transmutr | Skimp | Universal Importer | Decimify | FluidImporter | SimLab |
|---|---|---|---|---|---|---|
| Import formats | Yes (FBX, GLTF/GLB, USD/USDZ, OBJ, SKP, 3DS, DAE, STL, ZIP, folders, and common image formats.) | Yes (GLB, USD, SKP, FBX, OBJ, STL, DAE, 3DS, PLY, VRML.) | Yes (Very broad format list (Assimp-based).) | Partial (GLB and STL only.) | Yes (FBX, 3DM, OBJ, DAE, DXF, STL, 3DS, PLY.) | Partial (Requires one license per format.) |
| Clean hierarchy, units, scale, axes | Yes (Automatically handles unit conversion, up-axis mapping, and preserves component structure.) | Yes | Partial (Only scale units.) | No | Yes | Partial (Must be set up manually in advance in the settings) |
| Geometry simplification | Yes (Best simplification engine of the lineup (see benchmarks below).) | Yes | Partial (Basic optional polygon reduction on import.) | Yes | Yes | No |
| Advanced simplification | Yes (Magic simplification and per-object control.) | Partial (Automatically sets a default simplification level. No per-object control.) | No | No | No | No |
| In-SketchUp simplification | Yes (Edit and simplify objects already in SketchUp.) | Yes | No (During import only.) | Yes | No (During import only.) | No |
| Materials | Yes (Render-ready materials for SketchUp, V-Ray, and Enscape, including materials-only conversion.) | Partial (Base texture and UVs.) | Partial (Base texture and UVs.) | Partial (Base texture and UVs.) | Partial (Base texture and UVs.) | Partial (Base texture and UVs.) |
| V-Ray and Enscape proxies | Yes (One-click proxies, blob proxies, automatic billboards, and Enscape Asset Library export.) | No | No | No | No | No |
| Curated asset-source imports | Yes (Flawless imports for Poliigon, Humano, Poly Haven, and similar libraries.) | No | No | No | No | No |
| Convert multiple files at once | Yes (Batch conversion and automations, Command-Line Interface.) | No | No | No | No | No |
| Standalone converter | Yes (No need to load the heavy file into SketchUp when you don't have to.) | No | No | No | No | No |
Performance benchmark
Tested on the same real-world 1 million face model (either as GLB or FBX). Import time includes processing times for loading the source file into the UI, applying a 70% simplification (when available), and the final SketchUp file generation phase. User manual actions are excluded.
