      Hi
      Here is the Flow of exporting to mitsuba in my plugin.

      1.Create collada mesh without materials and transformation.(for instancing)
      2.Convert the collada mesh to serialized mesh by mtsimport tool.
      3.Export scene information iclude materials and instancing and transformation for serialized mesh.

      Please open "mitsuba_scene.xml" in mitsuba render ,if there is correct serialized mesh "mitsuba_main.serialized" created from "mitsuba_main.dae".

      That will be shown all correctly.

      Mtsimport work fine?
      Collada file created fine?
      Seriarize file is not zero byte?

        I can trap the create_directory error by appending at line 269 in mitsuba_main.rb
        the serialisation never occurs from the plugin...

        system(commandline, ;out => ['/tmp/log.txt', 'a'], ;err => ['/tmp/log.txt', 'a'])

        learn from the mistakes of others, you may not live long enough to make them all yourself...

          In my mac that occurs.

            YES it returns false

              Is this problem security permission?

                the problem seems to be the path from boost to the file not having the correct permissions, if that makes sense...

                As the folder is in the HD/Applications/ I have tried it at /tmp/, ~/Desktop, ~/Documents and in Plugins, all fail...

                my copy of boost lives in /usr/local/bin/include, but it's a symlink to homebrew/cellar so that my be the issue...

                not following symlink from ruby, I'll check it again from terminal...

                    Avoiding this problem,

                    I will write the code for serialized mesh exporter in ruby.

                    Thanks.

                      Good idea, it's probably the best long term solution...

                      you can PM me if you want anything tested...

                        I don't use a .bashrc file, i use .bashprofile, so I created one under User/me/.bashrc and it's not written to...

                        where is your .bashrc located, and exactly what does it contain??

                            thanks for that,
                            I found a note in the 'Mitsuba' source repository that the .bashrc file was no longer written to, so their message-box needs updating.
                            It does seem to be a simple path issue, that halts the process...
                            I just can't find it.
                            I have a separate instal of 'boost', so it may be a version/path conflict when Mitsuba calls it from shell...

                            Mitsuba works with other .dae files when imported, and I have older scene files from a previous instal, that run after they are auto updated on loading...

                            I'll remove my copy of boost and see if that makes a difference...

                                  Mitsuba seem work fine on my Sketchup 2014-Windowc 8.1 64bit
                                  But,
                                  How to implementing the clipmap/2D object in Mitsuba ❓ ❓

                                  http://s1.postimg.org/jtfu9opfj/image.jpg

                                  it won't appear in Renderer

                                  Hi sadyo.
                                  This problem is still exists.
                                  if it is clip mapped material ,please use mask option in "OTHER" tab of material editor.

                                  But the Image object is not material.
                                  So it can not edit by material editor.
                                  Please explode it to face and material.

                                  The image object is no supported in this plugin ,yet
                                  It will support in future version.
                                  But clipping of Image object will not be supported.

                                  And other notice,mitsuba render can not read TIFF and PSD.

                                  Thanks!

                                    downloaded v1.2.1 and notice you left the log code in...

                                    		system(commandline, ;out => ['/tmp/log.txt', 'a'], ;err => ['/tmp/log.txt', 'a'])

                                    not sure if it breaks PC's

                                          Does anyone have any genderal advice on installing mitsuba? I am getting a report that a dll is missing and installation stops. Basically I can find no proper install documentation. Thanks.

                                            did you try either/both of these window.exe downloads?http://www.mitsuba-renderer.org/download.html

                                            maybe some machine specs would help us out, helping you...
