PhysX 3.2.1 Heightfield Problem

Hi,

In the past few days I have tryed to create a HeightField in PhysX using the Samples and the “Users Guide”
But it still dont work.

My Creation Process is the following:

void CPhysic::CreateHeightfield(GLuint* intImageData, int size, PxVec3 Pos)
{
	PxHeightFieldDesc hfdesc;
	PxRigidStatic* HeightFieldActor;

	PxHeightFieldSample* samples = new PxHeightFieldSample;

	for(int i = 0; i<(size*size); i++)
	{
		samples[i].height = intImageData[i];
	}

	hfdesc.format = PxHeightFieldFormat::eS16_TM;
	hfdesc.nbColumns = size;
	hfdesc.nbRows    = size;
	hfdesc.samples.data = samples;
	hfdesc.samples.stride = sizeof(PxHeightFieldSample);

	PxHeightField* aHeightField = gPhysicsSDK->createHeightField(hfdesc);

	PxHeightFieldGeometry hfGeom(aHeightField, PxMeshGeometryFlags(), 1310, 1, 1);

	HeightFieldActor = gPhysicsSDK->createRigidStatic(PxTransform(PxVec3(0.0f, 0.0f, 0.0f)));
	PxShape* aHeightFieldShape = HeightFieldActor->createShape(hfGeom, *PlaneDefaultMaterial);

	gScene->addActor(*HeightFieldActor);
}

intImageData is an array wich is Initialized as followed:

GLuint* intImageData = new GLuint[2048*2048];
	
	for(int i=0;i<2048*2048;i++)
	{
		intImageData[i]=(unsigned int) ImageData[i];
	}

ImageData is an array of GLshort values.

I hope someone can help me.
