I'm confused Bagatelo. What are you asking? This is a plugin that will import .obj into SU. The inverse would be an .obj exporter.
Chris
Yes, I mistake. I have think about EXPORT model with obj file types. But .3ds is very good.
I try to import this model ( http://www.evermotion.org/modelshop/show_product/sculpture-01-am34/1806/0/0/ ) into sketchup and the plugin don't work properly. Export with 3ds Files from MAX result crash in Sketchup.
FBX files maybe can be de very best option.

I think it's stored as the VT entries.
ah yes here we go

vt u v w
Vertex statement for both polygonal and free-form geometry. Specifies a texture vertex and its coordinates. A 1D texture requires only u texture coordinates, a 2D texture requires both u and v texture coordinates, and a 3D texture requires all three coordinates. u is the value for the horizontal direction of the texture. v is an optional argument. v is the value for the vertical direction of the texture. The default is 0. w is an optional argument. w is a value for the depth of the texture. The default is 0.
Thanks - I see it now... wait for update...

Since I'm not going to pay $35 for a model of a small statue I can't see how the actual file is structured - looks like it might be very complex though !!! The current OBJ Importersare quite limited...

Cool, thanks TIG. I've been using Jim's importer for a long time.
One thing I've encountered with materials. You are assuming that the 'd' tag comes after the Kd tag, but it doesn't necessarily. It can show up anywhere in the list. The obj format doesn't require a specific order. So, if 'd' comes first, the plugin is crashing.
-
Thanks for the info... I'm looking at uv mapping to so a fix might be soon...
I also need to trap mtl's with a texture but no colour [using texture.average_color if no Kd ?]... I am looking at various fixes and other improvements... Please check out the Ruby Forum over the coming days... -
ok for some reason I'm not getting anything at all.
it's asking for the measurements, I see it reading lines at the bottom, it asks me if I want to flip Axis...then nothing appears on screen.edit : testing an idea. I think it's do to with the choice of measurements. hold on...
-
yup it's metres and kilometres.... looks like it's coming in so tiny you can't see it. (Inches, Feet, yards, Miles, Millimetres, Centimetres are working ok)
-
and I'm happy to report the UVmapping is now spot on
-
Tested also and it's working Great!!! Thanks TIG. I tried to import a few Lounge Chairs that I had for Vue in .obj format that crashed SU with the previous importer and the new version handled them flawlessly.
-
I have at last got working - texture mapping, units dialog, YZ-flip, crash avoidance etc etc...
Here's v1.2 http://forums.sketchucation.com/viewtopic.php?p=172790#p172790
Note that the file has been renamed and you need to delete any earlier ones...
It's still not perfect, takes ages with large files and large/complex/smoothed objs come out slow/messy/in_need_of_fixing...
Feedback please.

ok I'm getting strange results here. some OBJ's just won't import for some reason. Trying to figure it out atm.. the affected OBJ's will load into other app's ok tho, so I'm not sure what the issue could be.
Update.
the affected OBJ's import with Jim's Ruby ok (apart from flipped Axis and no UVmapping), so it looks like a bug somewhere..
want me to send you a copy of one of the affected OBJ's to test with?

Please send... Waht errors do you get in the console etc ?
Jim's code for the faces is effectively the same in both versions ???
-
thats the problem.. I'm not getting any errors (unless I'm doing something wrong the console window is remaining blank).... I'm just not getting the object...
the steps I'm getting :
select Ruby
Select OBJ
asked what unit's. (choose at random here)
Status bar shows the lines being readhere on a file that works I see the OBJ loaded. on a file thats not working, the view jumps, nothing is shown.
asked if I want to flip axis. (y/n)
no change in scene from start. - this also happens if I choose Metres or kilometers with an OBJ that does work ok. (obj will load as Feet...) the affected OBJ's will load with Jim's original script tho shrug
ok.. where do you want me to send the files to? I can't seem to attach them here...

Zip the file and attach it to a PM...

Hello everyon!!
Well,i'm trying this plugin and it seems awesome , but im having a problem with it, after the import nothing shows up..i mean sketchup makes the entire process ( count of the lines) and once SU finish ...nothing is displayed in the screen...it says " x number of lines processed" but the su file is clean as when you open a new file..so...m i doing something wrong? i'm trying importing a XFrog tree ,sometimes su ask me for to flip yz ,sometimes don't but no matter what option i select yes or not nothing works..., any clue ??
By the way my xfrog trees are in max ,i open them in max then i export them like an .Obj file format ..Could it be a max exporting issue that don't let the object importer works well with the xported Object??
-
In the other importers, once you import a model, you have to then click somewhere in the model to place the imported piece. Try that and see if it helps.

tried that Chris, no go.
with some OBJ's they are just not importing for some reason.. I've sent an example to TIG and I hope he can figure out why...
-
Yup , don't go placing it anywhere...let's wait if TIG find the tricky thing,I really hope so because the good 3d vegetation it's very important to achieve realism in renderings,that's why i need this plugin work perfect so bad.
-
Another thought, if you have them in Max already, why not export as .3ds?
-
Hey Chris , It's quite simple. There is a limited number of faces that the .3ds allows per model. The 3ds file format only supports 64 000 faces and the Highly detailed vegetation may contain more than 540 000 and a .obj supports that quantity of faceS. That's why can't converte my trees into .3ds. Well, i could import a Xfrog tree..but ....DAM !! THERE IS NOT TEXTURES...it's not supposed that this .obj Importer would keep the texture cordenates or the UV mapping?? iT WOULD BE IMPOSIBLE TO MAP 540 000 faces PROPERLY with a texture wich is a .tiff Leaf
