[PLUGIN]MITSUBA Render Exporter v1.5.0(20141109)

driven · 18 Mar 2014, 13:18

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

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'])

In my mac that occurs.

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

dyld; Symbol not found; __cg_jpeg_resync_to_restart
  Referenced from; /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
  Expected in; /usr/local/lib/libJPEG.dylib

Avoiding this problem,

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

Thanks.

driven · 18 Mar 2014, 15:36

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??

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"
fi

driven · 19 Mar 2014, 12:45

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...

Thank you very much!

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 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
