[Plugin] OBJexporter v3.0 20130131

Great work indeed. TIG, I thank you so much!
Here a test, downloaded from 3dWH. It's a ~1.5M faces mesh, ~20 mterials.
Imported in blender/cycles. Just playing, nothing serious. (yes, I forgot to add transparency on windows glass material)
A great free solution for rendering BTW. Having the support of blender editor, excellent solution for more organic adds.

A question to TIG. Now we're able to export tri meshes only. Obj supports n-gons as well. Will be possible to export like this? As b-mesh is the new implementation to blender. (the new n-gons editor-support)

I mean, SU UI seems to support flat n-gons. Is this true? I'm not convinced. Braking flatness results to tris (show hidden geometry)

THANK YOU, you are a life saver. SketchUp is the simplest 3D program I know how to use, finally, ARMA II modding here I come!

Thanks! Works great!

I use a Mac OSX 10.7.3 with SU 8.0.11751. OBJexporter.rb is in the 'Library/Application Support/SketchUp/Plugins' folder. When I start SU 8 I get a pop-up window "Load Errors" which says:

Error Loading File OBJexporter.rb
undefined local variable or method `book' for main:Object

Did I miss something, I am really new to SU? I see people here having OS X and SU8 without problems, so it should work.

TIG

You did not give the full folder path.
It should be the 'Mac HD...' root one - not the 'User...' one.
That said I don't think that's the issue.

The word 'book' doesn't occur anywhere in the code within the ObjectExporter.rb file, so the 'load error' is coming from either another file that's loading just before it which is itself causing an issue... OR the fact that the contents of the ObjectExporter.rb file have become 'corrupted' - have you put the .rb file directly into Plugins?, perhaps you have opened it with a wordprocessor and then saved it when closing [always use a plain-text editor], using a wordprocessor can reformat the file and cause issues, or perhaps the download itself was messed up - so does your browser download other .rb files OK, how did you download it exactly ?

There is no reason that this and many similar scripts should not work for you on this OS and Version...

goentiki

Mea culpa, this is really embarrassing: accidentally I placed an Alias into the plugin folder instead of the file itself. Now with the script in place it works well and I can import the obj into modo.

I also realized that the word 'book' doesn't occur anywhere in the script, but having no idea about SU programming I was confused.

Thanks a lot for your quick help and this great script!

Ok I have version 8 of sketchup and when I installed this nothing happened. I can still only export to dae or google earth.

Reread the instructions. It isn't an 'Exporter' in the sense of being a 'dll' which would appear in the Exporter's dialog list of types... rather it IS a script [it goes in the Plugins folder], and on a restart it adds a new item to the 'File' menu 'OBJexporter'...

That runs the tool...

BTW maybe this could be interesting for you as well if you use Blender (Cycles) to render:

Older versions with Sketchup 7 worked perfect.
But since I use the latest version of the OBJ exporter with Sketchup 8, then Sketchup always freezes while the exportprocess.
Tested it on Window XP 32 Bit and Win 7 64 Bit.

Then when I kill the Sketchupprocess in the Windows Taskmanager then a (sometimes) usable but incomplete new created OBJ-File is created anyway.

Does anybody know what could be wrong ?

Kind regards
Alain

TIG

Nothing similar reported.
Can you post [or PM] the SKP for testing...

Alain

Just wrote you a pm.
It's a File which was created in Sketchup 7 and then continued modelling in Sketchup 8.

I found out that when I explode groups then everything works fine.

Kind regards
Alain

TIG

The handing of instances/groups etc does take it a long time to check and compensate for it in UV-mapping and face orientation.
It does work... eventually - just have patience...

Hi i dont know how to insert the plugin if i put it in the plugin folder nothing happnes but if i open it with sketch up 8 also i cant import that

TIG

Hans

To install a script it needs its file [or for some other more complex scripts, its files/subfolder[s]] to be put into the Plugins folder and then to restart Sketchup, it auto-loads thereafter.

Questions to answer...

You are a MAC user ?
Are you putting the .rb file into the Macintosh HD/...Lib.../plugins folder, and NOT some other spurious ...User... folder ?

Have you read the tool's usage instructions and understand how it works ?

The 'OBJexporter' is found under the File menu and NOT under Plugins...

@Tig
Not really a problem but curious
When I want export something on the desktop, or anywhere folders / Subfolders, nothing is done!
No problem when I export in the SU Plugins folder or in a subfolder inside the SU Plugins folder!

Sounds like an issue with your System rather than the tool itself.
It exports fine into any folder, although it should default to the SKP's folder first off...
What are your security permissions/rights set to be ? 'Full' is best...
Also the other folders should allow files to be written to them 'by others' as it might be considering SUp/Ruby as 'not you' ???

Hello Tig ... Great tool thanks, I only have one problem, some files do not work, especially one quite complicated design file. Problem is sketchup crashes during the export and I get an incomplete file ...

When you say 'crash' do you mean a 'bugsplat'?
If so this is unexpected!
If you mean that the screen goes white and Sketchup becomes 'unresponsive' then it is probably still processing [use the Task Manager to see that Sketchup is still chugging away].
Under intensive processing it's a known issue that Sketchup becomes 'unresponsive' - left for long enough it should finish the task.
OBJ format is usually limited to specific objects or rooms, or buildings.
What are you trying to export? PM me the [zipped] SKP file if you can ?
To help the exporter please remember that only visible 'faces' [or images] are exported, so you can switch off layers containing unneeded objects like text/dims, also hide any other objects you are not interested in...
Many thousands of facets can be exported, the more nested objects the longer the export, the files get very very large...
