rendering problem irrlicht 1.7.1

It looks fine in irrEdit, then on irrlicht some triangles are missing (or are just black)

int main() {
	IrrlichtDevice *device = createDevice(EDT_OPENGL, dimension2d<u32>(1280,800),32,false, false, false, 0);
	IVideoDriver* driver = device->getVideoDriver();
	ISceneManager* smgr = device->getSceneManager();
	IGUIEnvironment* guienv = device->getGUIEnvironment();
	smgr->addCameraSceneNodeFPS();
	smgr->loadScene("images\\destroyers.irr");
	while(device->run()){
		driver->beginScene(true, true, SColor(255,100,101,140));
		smgr->drawAll();
		guienv->drawAll();
		driver->endScene();
	}
	device->drop();
	return 0;
}

I am guessing it has something to do with irrEdit uses irrlicht 1.5 to render (I think) and im using 1.7.1, but I still don't think that should happen... maybe a bug?

I have the same exact problem of some triangles being black, but in DirectX, and only when mipmaps are set to on.

hmm, if I set irrEdit to use the software renderer instead of directX, it has the missing triangles too

Maybe you could try normalizing the normals during the rendering.

Normalizing normals didn't change anything, and I'm not sure how to enable/disable mipmaps

i can't see the image

I uploaded the image somewhere else, hopefully you can see it now.

Everything seems to be working now... I just pressed a bunch of buttons in blender, converted to quads, and back to triangles, and poof, it worked

I assume you recalculated normals outside?

yep, I checked that, you can't see the triangle on either side, so normals wasn't the problem. Also, I began seeing the problem again, so I downgraded to Irrlicht 1.6.1 and its working fine.

What's the original file format of this mesh?
