First i would like to thank num3ric for creating the very nice Cinder Skinning block.

i managed to compile the code with only one minor change (changing from boost to std::experimental::filesystem::exists ).  
i also managed to compile the very promising FacialMorphTargets example and could still download the “Jane” asset from [http://www.facegen.com/sampleExports.htm](http://www.facegen.com/sampleExports.htm) .

The head gets nicely displayed, but the morphing does not work.  
I enabled the console and get the following warning:

|warning| cinder::gl::VboMesh::buildVao[477] Batch GlslProg expected an Attrib of USER\_DEFINED, with name vPositionDiff2 but vertex data doesn’t provide it.

maybe thats the reason the mesh doesnt morph ?  
i tried some debugging, but unfortunately i cannot make sense of the warning.

could maybe someone help out ? i would really love to get the face-morphing to work.

thanks alot in advance !

Try changing the `ABatchSection` construction initializer in `AMeshSection.h` from

```auto
mBatch( ci::gl::Batch::create( ci::gl::VboMesh::create( *source ), shader, mapping ) )

```

to

```auto
mBatch( ci::gl::Batch::create( *source, shader, mapping ) )

```
