Re: [osg-users] osgexport for blender?
Hi Jeremy, Just thought I would post to clarify the post about my exporter (This one: https://code.google.com/p/blender-osgexport-25/). I originally tried to update Cedrics exporter for blender 2.5 and got some way but realised that I couldn't follow it well enough to do it without introducing a heap of subtle bugs. So I started fresh and wrote that new exporter you found - but my intent was just to write a proof of concept that Cedric could use when he came to update his exporter - I agree that having 2 exporters is not the way to go and that Cedric knows more than anyone about osgAnimation so his exporter should be the way forward. I let Cedric know about my exporter off list and have been giving him updates on the progress so that he can pinch bits from it when he gets to updating his code to support animation. The reason I didn't announce this exporter anywhere (but google found it obviously) is that I don't want to create this confusion. That said - until Cedric has finished his updates if someone uses my exporter and finds a bug, post it in the google code project and I'll be happy to look at it. Regards, Damyon ... Thank you!

Re: [osg-users] osgexport for blender?
Hi All, Just to let you know that Cedric is looking at putting this script in a repository somewhere so we can track bugs/updates etc. He is just looking at the code first before deciding exactly what to do.

Re: [osg-users] osgexport for blender?
Hi Aaron If you found the 2.57 folder then you are in the right place - just create a scripts and addon folders in there. They wont exist at first unless you have installed some other script. So you should have: some path/2.57/scripts/addons with some path/2.57/scripts/addons/osgExport.py and a folder: some path/2.57/scripts/addons/osg/ with these files in it: __init__.py osgconf.py osgdata.py osglog.py osgobject.py (you may also have osgbake.py and osggui.py.del - but they are no longer used). If you use the install add-on feature it wont work because it will only copy the osgExport.py file. You need the rest of the files from the osg folder as well. Here is a link to the blender wiki page with the scripts folder location on all the different platforms: http://wiki.blender.org/index.php/Doc:2.5/Manual/Introduction/Installing_Blender/DirectoryLayout Hope this helps Regards - Damyon -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39903#39903 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgexport for blender?
Hi, Aaron If you click the checkbox and it doesn't change - that means there is a python error - this could be because it can't find all of the script files or some other reason. If you open the console it will show you the error. I think blender on mac uses the system console - which means if you open the Console application (Applications/Utilities) the error should show up there.

Re: [osg-users] osgexport for blender?
Hi Amigoface, Sorry - I think this commit to blender changed one of the import paths. http://comments.gmane.org/gmane.comp.video.blender.scm/22522 Ie - my blender auto updated and I had to change one of the import paths to make the script work - but obviously that broke the script for blender versions before the above commit. Here is an updated script that should work for blender versions before and after the above commit.

Re: [osg-users] osgexport for blender?
Hi Alberto, The script is for using within blender. Copy the files from the blenderExporter directory to your blender scripts folder. I'm on linux so my folder is at: ~/.blender/2.57/scripts/addons/ Then when you open blender you will need to enable the script. * Open the User Preferences window (Ctrl + Alt + U) * Click on the Addons tab * Type osg in the search box * Check the checkbox next to the Import-Export: Export OSG format (.osg) entry to enable the plugin. * Click Save as default to save the changes permanently. Now the File - Export menu will have an additional entry - OSG Model (.osg) which will run the script. Hope this helps - Damyon -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39854#39854 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] osgexport for blender?
Hi amigoface, Thanks for providing the model - I have updated the script and it works for this sample now. If you hit any more bugs let me know. I dropped the test and data folder from this tar file because they haven't changed and they are a couple of mb each.

Re: [osg-users] osgexport for blender?
Hi Serge, Thanks for reporting the problems and providing the model. Here is an updated script that properly excludes the animation update call if the mesh doesn't have NLA tracks. It also fixes the problem with the only selected checkbox. Seems to export and look just like the blender version. Amigoface - this should make your runway model export a lot better too - I don't have the model on this computer so I can't test it right now.

Re: [osg-users] osgexport for blender?
I have been plugging away at this script and have a much better version now. See attached. It works well for my simple tests - but I don't have many example models to try. Animations are supported as well as textures (either image or generated). It does not support animated materials like the old script does (mainly because I don't know how to create them in blender). If you have problems and want to report a bug - including the model will be a big help. I would still class this script as unstable - mainly because I haven't done too much testing - but if you have problems I'm willing to try and fix them.

Re: [osg-users] osgexport for blender?
Yep - it's not real stable right now. But I got the unit tests up and running on my copy now - (1 out of 5 passes) so I'll work on fixing them and post a new version. I also noticed when it's run from blender it saves the file to Scene.osg in the current directory regardless of the file you tell it. You may have seen that and thought you got no output with the default cube. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39467#39467 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgexport for blender?
OK - no problem - here is the current version with animations not working. I'm still looking at the animations - I'll post an update here when thats done.

Re: [osg-users] osgexport for blender?
I am working on a new version of the exporter - it works for static meshes, but not animations yet. It does support vertex colors, materials and textures. I'll post it as soon as I have fixed the animation problem. The animations are exported from the list of nla tracks - but they don't work yet. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39379#39379 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I have been testing a few more advanced models and have found some problems with the updated script - I'll take a look at it and see if I can fix it in the next few days.
