      Hi,

      think I found the problem, but not the solution...

      2014-03-18 11:44:26 INFO main [converter.cpp:127] Creating directory "textures" .. Caught a critical exception: boost::filesystem::create_directory: Permission denied: "textures"

      john

      Hi,john.
      Ummm...

      I guess the problem is delay of writing file.

      Please search "mitsuba_main.dae" in "/applications/su_render" folder.
      Tell me that file size.
      And Start Mitsuba and import "mitsuba_main.dae" file.

      Is there anything displayed on mitsuba window.

      Now "mitsuba_main.serialized" is created in that folder.and it is not zero byte.

      Seriarized file is binary mesh file of mitsuba render.

      Please send me your "mtsuba_main.dae" If "mitsuba_main.serialized" is zero byte.

      I will analyze it.

      Thanks.

        When I import that file, I get the attached popup dialog and the log contains the attached messages. The serialized file is then not empty and mitsuba generates a rendered scene! So the problem definitely involves getting from the dae to the serialized file. However, the rendering contains only one instance each of Components that have multiple instances in the SketchUp file. The handling of my original textured material also is weird (looks like a grainy mass of dots instead of the original wood image).

          hi

          dae is 54kb, fails to make texture folder...
          mitsuba_main.serialized is empty...

          if I import the dae into mitsuba, texture folder gets made on import, but is empty...
          mitsuba_main.serialized is 12kb
          plugins dae imported into mitsuba

            Here are the folders and contents after importing the dae. As John reported, the textures folder exists but is empty, as is the output folder.

              the other thing I tried was exporting a dae directly from SU...

              filesize 202 KB
              texture folder empty
              serialised 11 KB

              Sophie is facedown on the ground [I don't think she's partially happy about it...]

              she ain't happy...

                here are all the files for both...

                this is after the Misuba.app import so it has a textures folder...
                still empty after untitled was run...
                su_render.zip

                  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'])

                            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 just had a thought and did some tests...

                                    commandline tool need to modify .bashrc to point to python...

                                    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??

                                      I search in my mac.
                                      I found "bashrc" in "/private/etc"
                                      it contains this.

                                      # System-wide .bashrc file for interactive bash(1) shells.
if [ -z "$PS1" ]; then
   return
fi

PS1='¥h;¥W ¥u¥$ '
# Make bash check its window size after a process completes
shopt -s checkwinsize
# Tell the terminal about the working directory at each prompt.
if [ "$TERM_PROGRAM" == "Apple_Terminal" ] && [ -z "$INSIDE_EMACS" ]; then
    update_terminal_cwd() {
        # Identify the directory using a "file;" scheme URL,
        # including the host name to disambiguate local vs.
        # remote connections. Percent-escape spaces.
	local SEARCH=' '
	local REPLACE='%20'
	local PWD_URL="file;//$HOSTNAME${PWD//$SEARCH/$REPLACE}"
	printf '¥e]7;%s¥a' "$PWD_URL"
    }
    PROMPT_COMMAND="update_terminal_cwd; $PROMPT_COMMAND"

                                        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...
