Robert,
Thank you for your answer. I've checked what you pointed. But my exported model:
- Has no coulour array (just a material)
- Has 196 vertex and 196 normals (so probably no missing normals)
- And has no transparency
I really don't understand. Any idea?
Note that I load the model using the cache (ReaderWriter::Options::CACHE_ALL)
and that I duplicate it (in order to modify it without affecting the cached
object) by using:
myGroup = new osg::Group(*loadedCachedModel, osg::CopyOp::DEEP_COPY_OBJECTS |
osg::CopyOp::DEEP_COPY_NODES);
I also tried DEEP_COPY_AL but that has no effect. Anyway, I'm not sure it is
related to my problem...
I seen that on top of the geodes, there are MatrixTransforms with a stange
"StateSet { 0xba1 ON }" line (Exactly the same in each MatrixTransform), but
removing it didn't change anything.
If you want, the geode data looks like:
Geode {
UniqueID "Corps_geode"
DataVariance DYNAMIC
name "Corps_geode"
cullingActive TRUE
num_drawables 1
Geometry {
StateSet {
UniqueID Corps_stateset
DataVariance STATIC
rendering_hint OPAQUE_BIN
GL_BLEND OFF
Material {
DataVariance STATIC
ColorMode OFF
diffuseColor 0.300000011921 0.5 0.0 1.0
specularColor 1.0 1.0 1.0 1
emissionColor 0.111620302463 0.186033830047 0.0 1
shininess 24.5960784314
}
}
VertexArray 196 {...}
NormalBinding PER_VERTEX
NormalArray 196 {...}
PrimitiveSets 2 {...}
}
}
