[osg-users] [osgPlugins] Problems with dae plugin

Thu Apr 11 09:58:58 PDT 2019

Hello,

The Apple VR/AR philosophy seems to officially focus on DAE files. Unofficially it seems that other 3-D model files types are OK.

So, this solution strategy is very welcome. Thanks to the OSG community.

Ok, thank you, OSG ASSIMP seems to work for me.
I still don't have textures in OSG but also there are no errors, so it could be problem with the dae file itself.

It is pretty easy to build so I will recommend everyone to try this plugin if you have problems with dae. Just build, copy osgdb_assimp to osgPlugins directory and rename your dae file to .dae.assimp.
