Meshlab and assimp loaders works without any definition related to it. Is it because coordinates in the PLY file generated for right-hand coordinate system and those tools uses right-hand coordinate system by default? Some of the PLY files have "comment CoordinateSpace RIGHT_Y_UP" line which is most ...

I think it is related to opengl driver. Setting texture matrix of the material like the code below when using opengl driver fixes the problem.

core::matrix4 textureMatrix(1, 0, 0, 0, 0, -1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1);
mb->Material.setTextureMatrix(0, textureMatrix);

Rotating texture by 180 degrees solved the problem.

Edit : Flipping the texture vertically instead of rotating.

Only bottom part of the texture is being drawn on the model.

OK, fixed it in svn trunk r6133.
Thanks a lot.
Seems there is yet another ply format out there - this one using texture_u/texture_v for uv coordinates.
Somehow I never suspected parser. I thought those keywords were strictly defined. Sorry for the trouble.
Out of curiosity - do you know which ...

The ply-model has no uv-coordinates, so they all show a single pixel in the texture (in your case accidentally black, with other textures you get other colors).
Sorry, I should have sent one of the files I am working with. I think this one includes uv coordinates : https://github.com/acyildirimer ...

Sounds like your vertex-colors are set to black.
Try if doing something like this changes it: SceneManager->getMeshManipulator()->setVertexColors(model->getMesh(), irr::video::SColor(255,255,255,255));

Still the same. It is reproducible in 09.Meshviewer example if anyone interested.

I've tried to set texture manually but it is still the same.

//with light source
smgr->addLightSceneNode(0, vector3df(200, 200, 200), SColorf(1.0f, 1.0f, 1.0f), 2000, ID_IsNotPickable);
smgr->setAmbientLight(SColorf(0.3f, 0.3f, 0.3f, 1.0f));
model->setMaterialFlag(EMF_LIGHTING, true);

//without ...

I am trying to add texture support to PLY loader by copying relevant parts of the OBJ loader.
