I'm getting much the same error as John, though the message says "near line 25" instead of the line he reported. The /Applications/su_render/mitsuba_main.serialized file has size 0.

What can we do to help debug this?

MacBook Pro Retina, OS X 10.9.2

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

it won't appear in Renderer

Hi,

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

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.

slbaumgartner · 18 Mar 2014, 13:08

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

john

slbaumgartner · 18 Mar 2014, 13:17

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...]

driven · 18 Mar 2014, 13:28

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

tak2hata · 18 Mar 2014, 13:40

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?

driven · 18 Mar 2014, 14:08

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'])

YES it returns false

and if you use this version, you get the same error as the log file in Ruby Console...

Is this problem security permission?

driven · 18 Mar 2014, 15:14

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...

driven · 18 Mar 2014, 15:16

that returns

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...

driven · 19 Mar 2014, 00:00

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??
