      There is an important system file, named sketchup.rb which is shipped with SketchUp.
      It is in the ../Tools/ subfolder inside the main 'SketchUp' folder.

      If you have somehow deleted it nothing will load if it requires it.

      In v8 you should have at least these files in ../Tools/
      sketchup.rb extensions.rb langhandler.rb
      There might be other files too...

      These files should NEVER be found in the ../Plugins/ folder !

      The set up with newer SketchUp versions is slightly different, but the same principles apply...

        Thanks, a few folders got jumbled and files were accidentally duplicated (or got corrupted) that's why it didn't work.

          I have download so I'll export my models as test.
          I hope the results are good. 😄

          edit:

          It's works fine.

            i am using your objexporter to export my models to pepakura to make paper model of them. i am having this issue:
            if my model has different coloured faces like this:
            dd.jpg
            , exported obj file look like this in pepakura:
            Adsız.jpg

            and i am sure all edges connected. if i export kmz4 with skp6, i have no problems with pepakura. but you know sketchup 2016 is newer and faster than old one. i want to use the 2016 but this objexporting issue botters me. any ideas on this?

              OBJ exporters typically triangulate the 'mesh'.
              It's hard to see exactly what the problem is in 'Pepakura' ??

                  I have the problem that the OBJexporter sometime produces shading error like this:

                  Any suggestions how i can prevent this?

                    A little more info about what we are looking at, perhaps a SKP exhibiting the problem, or an OBJ/MTL/Textures ZIP ?

                    Otherwise it'll involve wild guesses...

                      The issue can be easily reproduced.

                      Build a face. Place two other faces on it an put another material onto these two faces.


                      http://picup.oliverlamm.de/files/IMG_2b4a64df798c484b7f040deabc7e0c36_36mzFlCf85_Ok_small.jpg

                      Save and export as .obj-file.

                      Import in Blender.
                      After remove doubles and limited dissolve you can see normals not standing in 90° on the face, which are causing these shading errors, i guess.

                      If needed, i can upload the used files.

                        Some examples files would be a very good idea - use ZIP for those non-compliant file-types...

                            The geometry is triangulated in the processing.
                            With this exporter and the Pro exporter as well.
                            Giving the face distortion you see.
                            It's not an option to NOT triangulate [unlike Pro exporter]
                            With no triangulation the distortion is not seen.

                              This means no chance to solve to problem?
                              Using the .dae export the geometry is also triangulated but there is no face distorsion.

                                This is an old plugin which is unlikely to be developed further.
                                Since the Pro exporter exhibits the same distortion issue with triangulated faces I expect it would not be easily solved.
                                Using the Pro exporter without triangulation sidesteps the issue but of course you may need triangulated faces for other purposes.
                                Why can't you use the native DAE Collada exporter ?
                                If that avoids the issue and you need an OBJ for some other reason does it export from Blender without distortion ?

                                  The Collade exporter works fine if the model has no texture.
                                  I'm looking for a way to export objexts with texture and import it to blender.

                                  When i use the .dae fomat the texture behaviour is very strang for example: textures dissapear when i join objects.

                                  I was very happy when i found die OBJexporter because it exports the modell and texture very well. Unfortunally these distorsions make it unuseable.

                                  Maybe i have to test the .stl exporter too.

                                    I build a model in sketchup. Then i export it as .dae file, import it in blender and use remove doubles and limited dissolve. After that i texturize the model.
                                    In this step, I often find minor errors on the model which i can't repair in blender.
                                    This means back to sketchup, fix the problem, export as .dae an so on.

                                    Therefore i had the idea to apply the texture directly in sketchup where i directly can fix these minor errors and afterwards export it to blender. But in this case i had the problem that the texture in blender dissappears when i join objects to do remove doubles and limited resolve just once. Without that step ich have to do remove doubles and limited resolve more than a hundred times

                                    This is why i'm looking for other ways to export the textured modell to blender.

                                      I downloaded your exporter and now trying to get my SketchUp model to Octane Render scene. But it asks for OCS/ORBX files (or whatever). How to do that?

                                      Thank you in advance

                                        Octane used to be able to import OBJ files.
                                        I haven't used it for a long time.

                                        It 'Opens' its own file formats- like OCS.
                                        It 'Imports' other file formats - like OBJ.

                                        Make sure you understand the difference between Open and Import...

                                          Hi TIG,
                                          Does this plugin do any sort of vertex welding? I am noticing that vertices are welded/combined somewhere in the import/edit/export process with the native SketchUp exporter. Of course for most people, it's a welcomed optimization but for me, I need to keep the vertices unique.

                                          Thanks 😄

                                            The first versions definitely didn't weld vertices. I recall vividly because it added extra steps for me when exporting. It doesn't look like any of those older versions are here though. You might find it floating around on the web in some older plugin repositories.
