[osg-users] Textured ply file is black when loaded.

['Tom Pollok' via OpenSceneGraph Users]

I converted the repaired obj meshmodel from 
https://groups.google.com/forum/#!topic/osg-users/BBUYMYiWGl8 using MeshLab 
to a ply file.

Pw: osg

I can load the ply file using MeshLab and CloudCompare, but when loading 
the ply file using openscenegraph 3.6.2 then i just get model that is 
completely black.

The header defines in a comment that there is a texture file:

ply
format binary_little_endian 1.0
comment VCGLIB generated
comment TextureFile Wareneingang_material_0_map_Kd.jpg
element vertex 99428
property float x
property float y
property float z
element face 186642
property list uchar int vertex_indices
property list uchar float texcoord
property uchar red
property uchar green
property uchar blue
property uchar alpha
end_header

But MeshLab did not create an mtl file, however as said, other tools can 
still load the model.

For loading i use:

osgDB::Options* opt = new osgDB::Options;opt->setOptionString("noRotation");osg::ref_ptr<osg::Node> node = osgDB::readNodeFile(pathToPlyFile, opt);
