[Plugin] OBJexporter v3.0 20130131
-
Some examples files would be a very good idea - use ZIP for those non-compliant file-types...
-
-
The geometry is triangulated in the processing.
With this exporter and the Pro exporter as well.
Giving the face distortion you see.
It's not an option to NOT triangulate [unlike Pro exporter]
With no triangulation the distortion is not seen. -
This means no chance to solve to problem?
Using the .dae export the geometry is also triangulated but there is no face distorsion. -
This is an old plugin which is unlikely to be developed further.
Since the Pro exporter exhibits the same distortion issue with triangulated faces I expect it would not be easily solved.
Using the Pro exporter without triangulation sidesteps the issue but of course you may need triangulated faces for other purposes.
Why can't you use the native DAE Collada exporter ?
If that avoids the issue and you need an OBJ for some other reason does it export from Blender without distortion ? -
The Collade exporter works fine if the model has no texture.
I'm looking for a way to export objexts with texture and import it to blender.When i use the .dae fomat the texture behaviour is very strang for example: textures dissapear when i join objects.
I was very happy when i found die OBJexporter because it exports the modell and texture very well. Unfortunally these distorsions make it unuseable.
Maybe i have to test the .stl exporter too.
-
I build a model in sketchup. Then i export it as .dae file, import it in blender and use remove doubles and limited dissolve. After that i texturize the model.
In this step, I often find minor errors on the model which i can't repair in blender.
This means back to sketchup, fix the problem, export as .dae an so on.Therefore i had the idea to apply the texture directly in sketchup where i directly can fix these minor errors and afterwards export it to blender. But in this case i had the problem that the texture in blender dissappears when i join objects to do remove doubles and limited resolve just once. Without that step ich have to do remove doubles and limited resolve more than a hundred times
This is why i'm looking for other ways to export the textured modell to blender.

I cannot thank you enough for making this exporter!!
You have literally saved me hundreds of $$$$

Hi, TIG!
I downloaded your exporter and now trying to get my SketchUp model to Octane Render scene. But it asks for OCS/ORBX files (or whatever). How to do that?
Thank you in advance
-
Octane used to be able to import OBJ files.
I haven't used it for a long time.It 'Opens' its own file formats- like OCS.
It 'Imports' other file formats - like OBJ.Make sure you understand the difference between Open and Import...

Hi TIG,
Does this plugin do any sort of vertex welding? I am noticing that vertices are welded/combined somewhere in the import/edit/export process with the native SketchUp exporter. Of course for most people, it's a welcomed optimization but for me, I need to keep the vertices unique.Thanks
-
The first versions definitely didn't weld vertices. I recall vividly because it added extra steps for me when exporting. It doesn't look like any of those older versions are here though. You might find it floating around on the web in some older plugin repositories.

Thanks for the reply. While I have you here, is vertex welding something that SketchUp does internally? I am having issues where I need to load an OBJ and then export the OBJ without any modification to the vertices at all. No optimizations for any reason as I render using texture arrays and need the unique vertices to set the texture index. I wrote a post in the main forum but nobody has replied yet. Figured I would ask.
Thanks
-
Looks like vertex merging was added in the latest version. Anyone know if we can find older versions?
2.9 20130130 Merging of shared vertices is now optional, as it slows processing
for larger models. -

I don't believe that is internal to SU. You might try using a different export format (like .dwg or .3ds format) and then convert to obj in a different app (like Blender or FreeCAD)

Where i can find the OBJexporter v3.0 20130131?? i can't find it anywhere
-
Please learn to do a bit more directed searching...
There are hundreds of useful tools in the SketchUcation PluginStore...
So try this: https://sketchucation.com/pluginstore?pln=OBJexporterNote that the very first post in this thread even includes a link to that very page !
https://sketchucation.com/forums/viewtopic.php?p=294844#p294844
i.e. the large button near the end of the post saying "Download"... -
xo i was trying to download it to OBJ, but everytime export it, it only export a third of the components. is there a max file? and can i fix this problem, so i can export it all in one go.
-
There's no limit, but the more faces the more time it takes.
How big is the file ?When you say it's missing out faces, can you explain fully.
Are there faces that are simply not there ?
Or are there faces with no materials ?
One possibility is that your model has reversed faces with textures on their backs, these will not show in most render apps. Either getting displayed as black, white or 100%-transparent faces.To see if there are reversed faces use View > Monochrome, with a Style that has a distinctly colored back-face color. If you see any back-faces, then they won't render properly.
It's best to ensure faces are properly oriented as you model using Monochrome and the context-menu > Reverse...
Luckily there are tools to try and fix such issues for you...
Try this one of mine... https://sketchucation.com/pluginstore?pln=FixReversedFaceMaterials
Please read its usage notes... -
I have been trying this exporter, and it works great, expect on components or groups that are mirrored or flipped. The normals are reversed. I have made sure that all the faces/normals are facing the correct way, before using this. They are. Any ideas?
-
This Exporter is quite old and it is no longer being updated.
However, a work around for your reversed normals in mirrored objects would be to use the Outliner to Select all of those Groups/Component-Instances and Explode them, then do the Export, then Undo the Explode ?
