HI Lokesh,
A Texture2DArray is something designed for shader work, the fixed
function pipeline won't access it so you'll need to write shaders for
it.
However, I can't see why you'd want to collection of images like you
have and apply using a Texture2DArray. These images all have specific
names suggesting that are associated with specific geometries in the
model. If you load an OpenFlight model it should load all the
textures it needs.
Could it be that you actually problem is totally different from the
problem you seem to be attempting to solve?
Robert.

Hi,
I have a flt model and multiple *.dds texture files in a Directory :-
my folder directory structure:-
my_folder
|- terrain.flt
|- road.dds
|- city.dds
|- building1.dds
|- building2.dds
|- building3.dds
|- building3.dds
|- building4.dds
|- building5.dds
|- banner1.dds
|- banner1.dds
I know how to read and apply single .dds texture file to my model
(terrain.flt) :-
Code:
osg::ref_ptrosg::Node terrainModel
(osgDB::readNodeFile(c:/my_folder/terrain.flt));
osg::ref_ptrosg::Texture2D tex (new osg::Texture2D);
osg::ref_ptrosg::Image image
(osgDB::readImageFile(c:/my_folder/road.dds ));
tex-setImage(image.get());
osg::ref_ptrosg::StateSet state=terrainModel-getOrCreateStateSet();
state-setTextureAttributeAndModes(0,tex.get(),osg::StateAttribute::ON);
but i don't know how to read and apply all these textures to my model
(terrain.flt).
my attempt :-
Code:
osg::ref_ptrosg::Node terrainModel
(osgDB::readNodeFile(c:/my_folder/terrain.flt));
osg::ref_ptrosg::Texture2DArray texArray (new osg::Texture2DArray);
for(int i=0;ifolder_files.size();i++)
{
osg::ref_ptrosg::Image image
(osgDB::readImageFile(c:/my_folder/+file(i)));
texArray-setImage(i,image);
}
osg::ref_ptrosg::StateSet state=terrainModel-getOrCreateStateSet();
state-setTextureAttributeAndModes(0,texArray.get(),osg::StateAttribute::ON);
but, it is not working. Help me.
Thank you!
Cheers,
Lokesh
