[Plugin] OBJexporter v3.0 20130131

When rendering in C4D my mesh gives strange results in the geometry around the area where I used Round corners plugin. I think it's because of the triangulation. Any suggestions?

I'm a poor blender user. However, in C4d, try to weld vertices. SU does insist to export non welded vertices. If C4d has some option like tris to quads or similar, give it a try. In C4d, select all the mesh and ask for something like recalculate normals, or normals outside or similar.
I know nothing about C4d but I'm sure, these functions exist, maybe under a different name.

Tig, thanks for a great tool to enable us to use the free SketchUp to export models to obj's to be used in Blender.

Is there a way to get the models to have all faces connected?
As of now i can't apply a subsurf modifier since all faces are disconnected.
I can load the obj in Mesh Lab and connect the faces, but is this the only way

Thanks again for your addon!

Cheers

TIG

Faces that form part of a smoothed Surface are exported somewhat differently from un-smoothed ones - with different #vertex normal# definitions for applied textures etc to appear smoothed etc ?
As far as I know the Pro tool does nothing more that that either.
What do you mean exactly by 'connected' faces ?
Can't this be done effectively in the receiving apps ?

Jakerlund

Yes, seemed like removing all doubles solved the problem in Blender.
Now i can apply subsurf and smooth objects.

Hey Tig,
When I put this in the 'Plugins' folder, it doesn't appear.
I have tried everything you said in other posts that have the same problem, but it didn't work.
I have Sketchup 8 and Windows 7.
Please help!

Are you saying it does not appear in the file menu?

Have you administration rights on your plugins folder?

Can you post a screenshot of your plugins folder?

And yes, I do have admin rights.

What Plugins folder is that? It isn't the one that belongs to SketchUp. You have to put the .rb file into the Plugins folder under SketchUp and not just the first folder you come across labeled Plugins.

C;\Program Files (x86)\Google\Google SketchUp 8\Plugins

Your plugins path should be as above

Thank you guys! My friend was at my house and he told me the folder in my pic was the right one (I had 2 plugin folders in that location and one was hidden)

Dave R

You shouldn't have two Plugins folders under Google SketchUp 8.

There is no option inside the plugin for "weld" the commun edges between faces ?

And if exist in another plugin, the fact to export with the present plugin will not "unweld" them ?

pilou

Does the OBJ export function from the SU Pro Version weld the edges for make volumes who can be subdivided in another 3D prog ?

After moving the .rb file into my plugins folder, I am still unable to export to OBJ. Is the newest version of Sketchup not compatible with this plugin?

TIG

It is fully compatible.
YOU must be doing something wrong.
After installing the file correctly in the Plugins folder and restarting Sketchup, the Exporter appears in the File menu... is this what's throwing you ?
Alternatively... if you don't have FULL security permissions to the Plugins folder, then you might have not installed it as you assume... is there a 'Compatibility Files' [or similar named] button-link in the Explorer Windows top bars ? If so click it...

Your report is not helpful - you assume we can deduce what is up from your bald statement that you are unable to export OBJ... Please consider the above and [re]read the tool's instructions.
Come back if you are still getting error messages etc...

Thank you very much for your plugin!

Unfortunately, I tested it with some models downloaded form the 3D warehouse, and the resulting OBJ has some texture missing (materials have no map_Kd), although they show fine in sketchup.
Any idea? I attached a small polygon cut from the original model if you want to test

incriminated part of the model cut out

I'd appreciate some insights on it
Thank You!

TIG

The model has been made sloppily - that's all.
If you use a Style with contrasting front/back default colors - say off-white/bright-blue, then view it in Monochrome mode you'll see some bright-blue faces - these are the ones that were not reversed properly and so they now have the material applied onto their backs, not the fron with is looking the wrong way.
An OBJ [and many other file formats] export will only include the faces' front material - in the case of the sample you provided that's the default off-white 'underneath' NOT the top which has a texture applied to the face's back, because it's made 'upside-down'

Find my Fix Reverse Face Material tool in the Plugins Index - that finds faces with materials on their backs and not fronts, reverses the face and remaps the back material onto the front face [that's by now facing the right way !]
After using the tool the model will appear no different, because the materials/textures will look the same - BUT re-view the model in Monochrome and you should see all faces in the default off-white, and it should then export properly with textured faces correctly oriented...

spattija

Thank you very much for your quick reply,
but I still have problems with it: the fix reversed plugin says that zero faces have been fixed. re-exporting it produces the same, non textured model.
Any idea?
