[osg-users] [osgPlugins] Trouble with texture to export to OSGJS format

[Jordi Torres]

Hi Mathieu,

You should use the gles plugin to export to avoid the Fatal nb colors error.
See: https://github.com/cedricpinson/osgjs/wiki/Convert-model-with-OSG.

For the images:

You can try to convert first your model to osgb and write the textures to
disk and then convert to osgjs using $osgconv file.osgb.gles file.osgjs, if
the osgjs plugin is not writting to disk the images.
Also you can save them as inline images in the same osgjs file. The
resultant file will be bigger though, but it is ok for quick tests. For
example drag & dropping here http://webkeux.com/osgjs-test/

One more thing, if you have the images as separate files you *must *use a
server (http server I mean).

Cheers.
