# V-Ray 3dsmax to V-Ray SketchUp with materials

By following these steps, you will convert a model from 3dsmax with V-Ray materials, to SketchUp while keeping the exact same V-Ray materials.

{% hint style="warning" %}
Due to limitations in V-Ray for SketchUp, some maps may not be converted properly. This is not something Transmutr can control. Transmutr simply writes the \*.vrmat data to the right place, V-Ray does the rest.
{% endhint %}

1. &#x20;Open file in 3dsmax.<br>
2. Disable Gamma correction, as V-Ray for SketchUp handles it differently (otherwise you'll get very dark materials).<br>
3. Export it as FBX.<br>
4. Split meshes by materials using the script "Detach by Material ID"\
   [Click here](http://www.scriptspot.com/3ds-max/scripts/detach-by-material-id) to download it, then *Scripting > Run Script*\
   ([Here](http://webcache.googleusercontent.com/search?q=cache:xh2fZaKaUcUJ:www.scriptspot.com/3ds-max/scripts/detach-by-material-id) is a cached version of the download page if it doesn't work)\
   \
   You need to do this to export materials as individual \*.vrmat files, instead as one big file.<br>
5. Go to "Tools > V-Ray vrmat converter", then "Convert Scene Materials to .vrmat" and choose the folder of the FBX file. This will create one sub-folder per material, with the same name as the materials.<br>
6. Optionally, copy bitmap files to the same folder as the FBX file, to help Transmutr find them.<br>
7. Load the FBX in Transmutr. It should automatically find all the .vrmat files exported earlier, and match them with the materials.<br>
8. Transmute, open your file in SketchUp, open V-Ray so that it can convert the .vrmat data to actual V-Ray materials.<br>
9. Done!
