Next version of Material Browser plugin will support Poly Haven's PBR textures, on SketchUp 2025:

SketchUp Make 2017 installers are still available for download on archive.org.

1.2.1 version:

• Brings compatibility with SketchUp 2024 & 2025.
• Tries to avoid conflicts with Fredo6's LOTT plugin.

Download latest Random Entity Generator plugin from the SketchUcation PluginStore.

@Pavol-Ivanko
Thanks for your report! I identified the issue, and it's super easy to fix.
I will push a new version of this extension compatible with SU 2024+.

SketchUp .style files are .zip files containing XML documents and images.
It should be technically doable to recreate the abandoned Style Builder.

@pilou Hello, how have you been since then?

I haven't set any hard limits in the Universal Importer plugin code... However, depending on your machine's specifications (especially the amount of system RAM), the import may be slow or even fail.

Or maybe the second retopology generates an invalid model.

Can you please send me the files directly in both resolutions? Because I don't wish to spend Tripo credits

Hi, thanks for your bug report.

I would be interested to have a copy of this STEP file (in private if you prefer) to confirm or not if this issue is macOS-specific

How did you install Universal Importer, using the Extension Manager or another method?

Could you please open the Terminal app on your Mac, paste the two commands below (one after the other), and send me their output?

xattr "/Users/brianroy/Library/Application Support/SketchUp 2024/SketchUp/Plugins/universal_importer/Applications/Mayo/Mac/mayo-conv"

"/Users/brianroy/Library/Application Support/SketchUp 2024/SketchUp/Plugins/universal_importer/Applications/Mayo/Mac/mayo-conv" --system-info

@vadhome I rented a Mac Mini M1 for 24H but I couldn't reproduce the bug shown in your screenshot, at least with macOS Sonoma 14.6.1. However, SketchUp 2025 crashed several times randomly when placing the model to import. I need to investigate further...

@MikeG73 I'm not sure to understand you.

Universal Importer isn't compatible with recent .blend files but this may change in the future

@sashapepperspray Thanks for the example model file! I successfully imported it with Universal Importer v1.2.6.
Something goes wrong on your system... You can try once again to reinstall the Microsoft Visual C++ library.

@Jorgensen, @L-i-am Thanks for your interest in this plugin I haven't abandoned it... I just have too many projects in progress

@sashapepperspray, @esthery Can you please send me (in private if you prefer) the source model you're trying to import?

@vadhome Hi! Someone else reported an issue importing CAD files (such as STEP) on macOS with Universal Importer. I plan to rent a Mac to investigate...

@shagrat Sorry, I didn't see your posts. I think it's too late now...

This issue could be related to importing a model from a remote server (here \\fileserver).

@sashapepperspray
The security software is just a clue, I don't know if that's the issue.

Using the Windows File Explorer, can you please access this folder:

C:\Users\tenen\AppData\Roaming\SketchUp\SketchUp 2024\SketchUp\Plugins\universal_importer\Applications\Assimp\Win

Run assimp.exe and then report to this thread any errors you see.

@sashapepperspray
Can you please confirm that the latest Visual C++ Redistributable x64 is installed on your Windows? Here is a reference screenshot:

Hypothesis: You have a security software that blocks the Assimp executable (assimp.exe) when it tries to access the file system

@sashapepperspray Do you have Windows 10 or Windows 11? Are you Administrator of your OS?

@sashapepperspray This error message indicates that the bug occurs when a polygon reduction is requested, in the SU viewport, with the plugin toolbar... but I don't know why.

Have you succeeded in this operation with other 3D models? Or this operation fails everytime, whatever the 3D model?

Hello @MikeG73

Thanks

Indeed, BLEND format support in this extension is limited to older .blend files and one must claim then map the textures manually...

I hope to improve that in the future

Cheers!

@RLGL
I think it's fine now. I imported with the Universal Importer v1.2.6 many STEP and IGES files from McMaster Carr and their scale is everytime correct in SketchUp. Be sure to let millimiters as "Source model units" when importing...
