[Plugin] Import OBJ with Materials v2.1 20131118

[mingjae]

Hello,

i need a help sir, the plugins wont load the .obj file,
but at the text box bottom of sketchup it processing something but just in a second..
my .obj file is around 6Mbs

I am trying all the 3 methods,with textures,no material, and as mesh but no object were created, the obj_importer.rb is on the plugins folder at Google Sketchup8 directory,
and the plugin menu is loaded at the SketchUp>Plugins..

my OS is Windows7 Ultimate 64bit,
my Trimble SketchUp8 ver is 8.0.16846

on larger .obj file (76Mb) the plugin processing about 4secs but still no object were created, did I miss something to load the models?

thx

The Fluid OBJimporter is better and faster.
If your OBJ file is in say 'm' and you import as 'mm' the geometry size can be so small nothing is created.
Some OBJ files also have incompatible formats...
A 6Mb file should take some time to load.
If you have the Ruby Console open are there any messages...?

yes mr.TIG, fluidImporter can successfully load .obj models but it 90% will crashes if i try to render the scene using vray,

and yes, there's a lot of text if i open the ruby console, these are the texts written:

Processing 'C:\Users\John\Downloads\Compressed\VizPeople_Free_3d_Models_Sofas\Ikea_kramfors\Ikea_kramfors.obj'...

I try another .obj files and still wont load the models,

here is one of the model sir:

Try to model without V-Ray loaded and see if you get less issues then.
I wrote V-Ray Tools so I could disable V-Ray under Preferences > Extensions and then load V-Ray only when I need to render. Makes SU start faster and avoid various issues that VfSU causes.

Hi! Very usefull plugin BUT it appears it isnt working for me. I run it, select my .obj click OK and then Nothing! Just as if I didnt do anything! What could be wrong?

What units does the OBJ file use?
Try assuming they are 'meters' - this 'biggest size' is more likely to work and avoid 'tiny geometry failures'.
Are there any Ruby Console messages ??
Do you have a small OBJ file you can share [+MTL?] ??
Because you are on Windows have you considered using the faster Fluid-Importer that has just been discussed here - it's faster too...

[John514]

I export a .FBX file with bake occlusion through LightUp (demo)
Then I convert it to .obj with Autodesk`s converter and I try getting it back to sketchup.
So yes the units were meters when I created it.

Here is my Ruby messages. It appears there is an error:

That (ΓΙΑΝΝΗΣ) thing is my username! Its Greek.

Might be an issue with Unicode characters. Try using a path and filename with only Latin characters.

[John514]

You were right! Thank you. The textures didnt show up, but I`ll try a new export and see how that goes.

[John514]

It seems that the materials wont import. I`ll try some other things latr and post th result.

Hello
I do not quite understand how they think that with the FixtreeD.rb it does not work for me really what am I doing wrong?
Have saved the tree and saved as skp and tried to open their tool is not
Can you please help me
greeting
Tobi

[TIG]

@Tobias

You post doesn't make much sense.
Please try rephrasing it and logically explain your problem.

[Birner]

Hello and Excuse me please!
I'm from Germany and my English is a little rusty.
So my problem lies in the implementation of the import OBJ files of tree[d] generator.
So I followed their instructions inserted into the missing images folder and tried to import but it does not work for me.
I also downloaded and installed your FixtreeD.rb but somehow everything works for me does not.
Maybe they have a video how does that make exactly would be really great
greeting
Tobias

[TIG]

@Tobias

Now I understand [a bit].
Ensure the OBJ and MTL files are in the same folder.
Make sure the missing image files - as they are listed in the MTL file - are named exactly as the ones in the copied folder [folder/image].
Also ensure that the copied folder is with the MTL and named as the folder in the MTL images' paths...

Once we have an imported OBJ file with textures applied we can talk about the issues that the tool tree[d] can create...

[Birner]

Hello
Yes, I created a folder that I have 3D tree gennnt since I have the OBJ file and MTL file the two images so inserted the bark and the leaves.
Well hope it's the right thing?

Hi
I tryed to import in SU 2013. Nothing happends, the obj seams not to import. Not working on SU 2013?

[TIG]

It works in v2013 just as it did in v8.

Do you mean you can import the file in v8 but it fails in v2013 ??
If that is the case, what other plugins do you have in v2013 compared to v8?

Alternatively...
What is this OBJ file you are importing?
Can you open it in alternative apps like Blender?
Any errors in the Ruby Console?

Can you get this very simple test OBJ to work in v2013?
Extract the obj & mtl from the attached ZIP.
For simplicity there are no textures, only colors defined in the mtl
It's a 1m cube, units are Meters with YZ flipped.
Its RGB colored faces are on the axes.
I just retested it in v2013 and it worked fine.

PS: Please update your User-Profile with OS, Version etc - it helps us help you...

Thanks TIG
It works. I found out the problem on my files: It was a path with an bad letter: ö! I correct this and now your importer works fine!!
Thanks and sorry for trouble.

[TIG]

That is an important point.
SketchUp's older version of Ruby on PCs doesn't care for non-ASCII characters in folder/file-paths...
Making it return an incorrect 'false' when testing that such a file exist?...
Many plugins can fail because of this.
