OBJ+STL import export

rray · Post by **rray** » 01 Jun 2017, 20:04

I've been needing a faster OBJ export lately, so I wrote this exporter&importer for OBJ, and thought I'd share that.

It supports zbrush polypaint and painted mask (note: zbrush does now import polypaint too)

Also ex&imports STL binary and ascii, and imports PLY (latter experimental, unstable)

see https://github.com/specularity/softimage/releases

requires a restart

Thanks rray! I'll give that a try. You're previous .stl importer has worked perfectly and very fast.

Version 2
- progressbar fixes
- obj format should be much faster now (uploaded a debug version of the dll by accident last time resulting in >50% speed drop)

That's pretty useful ! Both for fast OBJ in/out, and making STLs, or importing some that are around!

Wonder if Vitaly Bulgarov is roaming around, he'd be delighted to have his import export hotkeys use that instead! ( As well as SItoOctane if not already using that )

Hello rray thnx for the upgrade, the obj exporter is crazy fast: 10,5 mil trs mesh about 45s

Default exporter after 2m30s still on 20% , at 4 mins progress bar disappear not responding etc. If i dont touch it it might do the job in 10 mins who knows.

Now tbh so far i never used your import is the first time i try it :
OBJ default importer on same mesh did 1m41s, addon 2m08s
Also i found an obj that crashes with it

Still thanking you for stl import/export gr8 job

Glad to share that stuff! @FXDude I was wondering the exact same thing while watching the gnomon talk!

Then again he's using it for subd modeling mostly, which maybe isn't that heavy. From the talk I got that he uses the Octane standalone, and is swapping out object files. The plugin is really powerful, and he could add hair to his models now what a nice combination

@mc_axe the default exporters were developed before they added the fast import/export API, I wonder why they were never updated with that.

Is it my importer crashing btw or the default one? If it's mine I wonder could you pm me the file or any other file that crashes it?

just fixed an 1 off error when reading obj which broke polypaint import. Might have caused the crash too. All links are updated
--------
mc_axe's crash was because of a bug in my importer. when the obj files contains a whole scene with some objects that have uvs, and some that don't then i crash. working on a fix
--------
should be fixed now

Hey, I don't mean to necro a thread here but just incase someone else has the same issue I had with the plugin I will post my fix here.

I had an error when trying to export an STL file which read:

// ERROR : Object doesn't support this property or method

I fixed it by changing the line 498 from

Code: Select all

bExportBinary = (GetValue("preferences.File Format Options.STL_Format") = 0);

to

Code: Select all

bExportBinary = GetValue("preferences.File Format Options.STL_Format");

Not sure why this caused an issue but no matter, I am relieved to have a workaround

May help someone someday

luceric · Post by **luceric** » 30 Aug 2019, 01:28

it was probably meant to be bExportBinary = (GetValue("preferences.File Format Options.STL_Format") == 0);
which, if that's correct, would be the oposite of your fix

rray · Post by **rray** » 30 Aug 2019, 12:08

Thanks for the heads up (and using the plugin) !
Indeed "==0" as luceric mentioned. Fixed it at some point but didn't upload any new releases after that!

(new release is uploaded now)

Btw the last version also supports replacing the selected object when importing obj and stl

The selected object stays the same scene object, but internal geometry is switched to the one from the file. This could be useful if the object is used in an ICE trees etc as this would require no changes to the scene.

Thank you for the fix

looks good now.

Just updated this plugin. Point order is kept now when importing OBJ. The importer can be used to import zbrush meshes, rig & pose in XSI, then send back to zbrush as a base mesh without GoZ.

Thanks a lot!

This + PolyPaint support saved my day!
Thank you

BTW. sometimes polypaint not working by default, I have to append that just exported obj, project only colour on it(they are exactly same polygon), and export again, and it work...probably my own fault.
