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

[Chris Hanson]

That's where my expertise ends.

That COLLADA library is the anti-Christ.

If it doesn't work, consider building Rui Wang's OSG ASSIMP reader/writer (
https://github.com/xarray/osgRecipes/wiki ) which uses a different and
probably better-supported COLLADA/dae library.
