Found no matching material for Group in 3ds file.

I encountered this reference : Found no matching material for Group in 3ds file, when I try to run a irrlicht program in visual studio.

Code: Select all

 
        scene::IAnimatedMeshSceneNode* anms =
        smgr->addAnimatedMeshSceneNode(smgr->getMesh("../../media/ballance.3ds"));
 
    if (anms)
    {
        scene::ISceneNodeAnimator* anim =
            smgr->createFlyStraightAnimator(core::vector3df(100,0,60),
            core::vector3df(-100,0,60), 3500, true);
        if (anim)
        {
            anms->addAnimator(anim);
            anim->drop();
        }
 
        anms->setMaterialFlag(video::EMF_LIGHTING, false);
 
        anms->setFrameLoop(0, 13);
        anms->setAnimationSpeed(15);
 
        anms->setScale(core::vector3df(2.f,2.f,2.f));
        anms->setRotation(core::vector3df(0,-90,0));
        anms->setMaterialTexture(0, driver->getTexture("../../media/sydney.bmp"));
 
    }
 

I tried to replace ballance.3ds with another 3ds model like room.3ds, which runs well.
I am a irrlicht beginner. Can you tell my why? I'm so frust confused about it .
Thank you.

Well, this simply means that your 3d file contains either a buggy material definition, or some unsupported type of material that cannot be used together with Irrlicht.

you mean what is the problem? code or 3ds model?

I think the ballance.3ds model may rely on some material which can not found in current directory.

3ds materials are contained in the same file. Otherwise this failure might occur. Or, as I said, an unsupported type of material, which would be kind of a bug in the code (Irrlicht's code to be precise). But in most cases you can safely ignore this, as a standard material should be used. But it might be better to fix the model here, to have predictable results which match closer your inteded results.
