      Hi Samuel,

      Since I updated to v1.1.8, I always got this message:
      bug v118.jpg
      It happens no matter the file or its path, or the file format. In the above case, the file gou.mtl exists at the correct location.

      Any idea ? Do I have to uninstall the previous version ?
      Thanks in advance,

      DB

        @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.

          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.

          Thanks for your help

            Hi
            I have installed Universal Importer today.
            I am rather used to installing plugins but I guess I may have missed something.
            Whatever the file or file type I try to import, I get an error message.
            Regards

              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

                Hello,
                I undestand for STEP format lower compatibility.

                As you suggested, I have tried with two obj files found on 2 different web sites.
                It works for one, it does not for the other one.

                Please see error message in attached file.

                Feel free to provide me link to test obj files. I may test them if you think it helps.

                Best regards

                  Hello @satemorej

                  The compatibility with the OBJ format is high.

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

                  https://sketchucation.com/forums/download/file.php?id=168290&mode=view/rokbox.jpg

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

                      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.

                        Hi Samuel,

                        Thanks again for this cool plugin 😄
                        I use UniversalImporter to import an OBJ file that is exported from MeshMolder.
                        As you can see on the images, 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.
                        Do I miss something or is there a face count limit in UImporter ?

                          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?

                            Hi Samuel,

                            I'll try with a 200k faces mesh as time permits.
                            I've tried with TIG's "OBJ Importer" plugin and it doesn't decimate the triangles. Cool 😎

                              Hi Samuel,

                              Here are the results with a 200k triangles mesh:
                              1.jpg
                              2.jpg

                              The triangles loss is far less than with a 400k mesh, but it is still there.

                              Regards,

                              DB

                                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,

                                    Thank You for making this plugin available to the public, I would really like to try to use it, unfortunately sketchup crashes on import. I tried with multiple formats of the same model with no success:/ I’m using sketchup 17 make version.

                                    Best regards!


                                    This is the file name

                                          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.

                                            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 😄
