Transmutr vs Decimify
Transmutr vs Decimify for SketchUp: compare 24s vs 155s import, simplification quality and control, file formats, materials, proxies, and pricing.
Transmutr and Decimify are both powerful tools for simplifying and importing 3D models into SketchUp. While Decimify is limited to importing GLB and STL, Transmutr supports a wide range of industry-standard formats. It is also much faster, and offers advanced geometry simplification, render-ready materials, and one-click V-Ray and Enscape proxies.
Where Transmutr is stronger
- Many more import formats than Decimify (limited to GLB and STL)
- Transmutr is over 6x faster than Decimify (see benchmarks below)
- Clean hierarchy and control over units, orientation, and scale
- More control over the simplification process
- Render-ready PBR materials and one-click V-Ray and Enscape proxies
- Flawless imports for common asset libraries
- Convert multiple files at once
When Decimify still makes sense
Decimify has a free version limited to 30% simplification.
Feature comparison
| Feature | Transmutr | Decimify |
|---|---|---|
| Import formats | Yes (FBX, GLTF/GLB, USD/USDZ, OBJ, SKP, 3DS, DAE, STL, ZIP, folders, and common image formats.) | Partial (GLB and STL only.) |
| Clean hierarchy, units, scale, axes | Yes (Automatically handles unit conversion, up-axis mapping, and preserves component structure.) | No |
| Geometry simplification | Yes (Best simplification engine of the lineup (see benchmarks below).) | Yes |
| Advanced simplification | Yes (Magic simplification and per-object control.) | No |
| In-SketchUp simplification | Yes (Edit and simplify objects already in SketchUp.) | Yes |
| Materials | Yes (Render-ready materials for SketchUp, V-Ray, and Enscape, including materials-only conversion.) | Partial (Base texture and UVs.) |
| V-Ray and Enscape proxies | Yes (One-click proxies, blob proxies, automatic billboards, and Enscape Asset Library export.) | No |
| Curated asset-source imports | Yes (Flawless imports for Poliigon, Humano, Poly Haven, and similar libraries.) | No |
| Convert multiple files at once | Yes (Batch conversion and automations, Command-Line Interface.) | No |
| Standalone converter | Yes (No need to load the heavy file into SketchUp when you don't have to.) | 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.
Import speed
- Transmutr: 24s
- Decimify: 155s
Simplification quality
- Transmutr: 5 / 5
- Decimify: 4 / 5
Simplification quality
Decimify is slower than Transmutr, but the quality of the simplification is comparable. It also offers less control over the simplification process.
