can't load the texture on the animated mesh in ios

[anirban]

I am trying to develop an augmented reality application in ios using vuforia and irrlicht. I am able to place a 3D animated object on an image target,but I am not able to load the texture of the model. The model appears white when i run the app. Can anyone plz help me with this? I am pasting my code snippet where i loaded the mesh and the texture below.

Code Snippet

device = createDevice(video::EDT_OGLES1,dimension2d<u32>([UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height),16,true,true,false,0);
driver = device->getVideoDriver();
smgr = device->getSceneManager();
guienv = device->getGUIEnvironment();
mesh = smgr->getMesh("sydney.md2");
mNode=smgr->addAnimatedMeshSceneNode(mesh, 0, 1 | 2);
mNode->setMD2Animation(irr::scene::EMAT_STAND);
mNode->setMaterialTexture(0, mDriver->getTexture("sydney.bmp"));

Are you sure that texture is POT?

Hey Nadro,
Previously I was using OGLES1. Now, I am using OGLES2 and Vuforia along with it. The 1st time when drawall() is called, the texture appears. From 2nd time onwards, the texture disappears and the model appears black on the screen.
And yes, the textures are Power of Two.

Maybe Vuforia change some OpenGL states?

Hey Nadro,
Thanks for your help. Yes, the Vuforia changes the active program and active textures. So, I had to again bind the appropriate ones. I again need your help. Is there any way of loading POD files in irrlicht? Till now, I have only loaded md2 and obj models.

We have no POD loader so far. We have: b3d, bsp, collada (dae), csm, dmf, lmts, lwo, md2, md3, my3d, obj, oct, ogre, ply, smf, x, stl and .irr loaders. There's a few more loaders out there from others, but haven't seen a pod loader yet - so you would have to code that yourself.

hey cutealien,
thanks for ur reply. Actually i want to render a complete scene consisting of multiple nodes interacting with each other.can u please suggest me a feasible way of doing it?

[CuteAlien]

Some people use irrEdit to create scenes. Some might use Collada. Personally I tend to use a custom xml file and sometimes a custom (rather game-specific) editor I wrote myself. There's are more solutions (several editors have been in development in the forum), but it always depends on your game which way works best. I think for shooters for example there are some bsp editors which can probably also be used (never did a shooter myself with Irrlicht, so not much experience there).

I have the same problem. How do i "bind the appropriate ones"?
