Could you also include Revit .RVT import with textures as well?????

There is little chance that the RVT (Revit) format will ever be supported by the Universal Importer plugin.

However, there is a paid add-in for Revit that allows you to export a Revit model and its textures to SketchUp.

1.2.2 version deletes temporary hard links and temporary files possibly left after an import fail or a polygon reduction fail.

Here's a simple cube saved in Blender 3.5 that fails to import...

Indeed Rich, Universal Importer passes Blender 3.4.1 cube test but not Blender 3.5.0 one.
Thanks for your report

Hello, I am pleased to announce the availability of Universal Importer 1.2.0! Here are the changes brought by this new version:

Improvements

Imports are faster due to the fact that the plugin now uses (as much as possible) temporary hard links instead of classic temporary files. This also allows to monopolize less disk space during the import process.

I refactored some of the plugin code to make it cleaner, I hope so

Bugfixes

Polygon reduction from the toolbar was not working anymore (or not for all models). The number of faces before and after reduction was about equal, very far from the target... It's fixed!

Thanks to the great work of the Assimp contributors, you should no longer get the error:

• "End of file or read limit was reached", when importing a .ter file (Terragen).

• "Constructing BlenderDNA Structure encountered an error", when importing a .blend file. By the way, the files created with Blender 3 are now importable provided you:

  1. Extract the textures embedded in the .blend file to the disk with Blender.
  2. Check the option "Claim Missing Textures" in Universal Importer.

The bug of imported materials with zero opacity is fixed. Thanks to JDD for reporting this bug.

It is now possible to load an .obj file that references an empty material library ("mtllib"). Thanks to Jérôme Tas for reporting this case.

A heavy model (e.g. more than 400 000 triangles) can lose triangles once imported into SketchUp with Universal Importer. This problem has not disappeared yet but seems less present... Thanks to Didier Bur for reporting this problem.

Translations

I took the liberty of including a Japanese translation of Universal Importer, found on the PC-Trace blog. If you are the administrator of this blog, I invite you to contact me to become the official Japanese translator of the plugin.

If Universal Importer is not available in your native language, feel free to contact me to become its official translator

Still getting errors even on simple cube mesh. No materials, no modifiers and no external files linked or appended to .blend

Hi Rich,

Thanks for your quick bug reports.

Does Universal Importer v1.21 allow you to import other formats than .blend?

Can you please attach this very simple .blend file that refuses to be imported?

1.2.1 version handles the case when you import a model from a non-system disk partition such as "D:".

This is on Blender 3.2.1 files. Even a simple cube fails

Hello Rich,

This error is fixed in upcoming Universal Importer version! In fact, even current Blender version (3.4.1) will be somewhat supported. More news on this topic very soon

Hello Jérôme,

Upcoming plugin version fixes this error!

@bartektrebacz said:

Dear Samuel,
Thank you for making this plugin available to the public

Dear bartektrebacz,

It seemed natural and more "ethical" to release this plugin for free because it relies heavily on free public resources (such as Assimp and MeshLab) that are developed by other developers than me.

@bartektrebacz said:

[...] SketchUp crashes on import. I tried with multiple formats of the same model with no success I’m using SketchUp 17 Make version.

SketchUp 17 Make, OK. Can you please send me the file "uploads-files-955134-F22+ANUK.3ds" via Dropbox (or another file host) so I can inspect it?

@didier bur said:

I use Universal Importer to import an OBJ file that is exported from MeshMolder.
[...] the 435488 triangles from MM are converted to a 86702 triangles mesh in SU. But when importing, UI does say "The file has 435488 faces. Do you want to reduce the number of faces ?". The triangles decimation occurs even if I answer "No" to this message.

@didier bur said:

I've sent you the OBJ file via PM.

Hello Didier,

Thanks for providing this OBJ file. With upcoming version of Universal Importer, I ended up with 379808 faces in SU. Not perfect but better

Hi Didier,

I meant to say export the model to 435,488 faces from Meshmolder, then target 200,000 faces with Universal Importer to see how the plugin behaves... but never mind.

In your case, the polygon count goes down even if you don't ask Universal Importer for a reduction. This leads me to think that it is solely the conversion (done thanks to Assimp), which by an automatic optimization or correction, causes the loss of triangles.

Could you please send me the model you are trying to import?

Regards,

Hi Didier,

No, I didn't put such a limit in the Universal Importer plugin.

For information, polygon reduction is done thanks to MeshLab.

If you target 200 000 faces when the plugin proposes a polygon reduction, what is the final result in SketchUp?

If I understand well, you use a custom collection of .skm files?

Today, plugin categorizes materials automatically depending on a subtype-type dictionary... For example: "D:\Textures\Floor\Red Marble 02.skm" is categorized automatically in "Stone" because of "Marble" word.

Do you think it would be more relevant if plugin categorizes materials depending on filesystem hierarchy? We could filter materials by categories with a classic tree view at left.

Hello Jérôme,

I inspected the ".obj" file mentioned in your last message. It contains an empty "mtllib" statement, on line 7. This causes the "copy_stream" error...

While waiting for a fix in my plugin code, here is a workaround:

• Open the file "Bearded guy.obj" with a simple text editor.
• Delete line 7 (mtllib) then overwrite the file.
• Import the file again with the plugin.

Hello @satemorej

The compatibility with the OBJ format is high.

Can you, please, send me the files producing this error?

I would like to inspect every file (.obj, .mtl and textures) in the archive you downloaded.

@satemorej said:

Hi,
I have just installed Universal Importer.
I guess I missed some setting steps as whatever the file I try to import, there is an error message.

SKETCHUP PRO 2017 / MACOS Catalina

Thanks for your help
Best regards
Jerome

Hi Jérôme,

Did you also try to import a file in a "popular" format such as OBJ, FBX or glTF?

Compatibility with STEP format is low else broken... See this issue on GitHub.

Best regards,

Samuel

first problem:
made a box
to copy node, 6 copies
to move node, moved some distance
now, i have something line this:
■ ■ ■ ■ ■ ■
how do i make a solid group of all these copies?

Do you mean put many groups in one group? If yes, there's a "Make group" node for that purpose. Then check Outliner panel...

@whiteshadow said:

another problem:
is there a way to randomly move copied opjects between a set range (distance between 2 boxes can be anything from 3 to 10, random distance between every copy)? if yes, how?

eg:
instead of getting
{■ ■ ■ ■ ■ ■},

how can i get
{■ ■ ■■ ■ ■}

There's at least a way. Look at this "Random Gap" parametric schema, attached below to this post:

It's no yet documented but "Move" node accepts formulas to set dynamically X, Y and Z positions.

In formula: x + a + rand(b,c)

x is X position of Box in loop
a is Self Width of every Box
b is Min Gap between Boxes
c is Max Gap between Boxes

Random Gap.schema.zip

@Rich Thanks for your report.

.blend v3 files are no yet supported.

And .blend v2 support isn't very good, but next Universal Importer versions will support them better

In meanwhile, if you have only a .blend file as source: I recommend to first export this source to .fbx or .gltf from Blender, because FBX/glTF support is rather good in current Universal Importer version.

1.1.9 version fixes import of textures stored in non-system disk partitions, e.g. D:\path\to\texture.jpg
