   Lighting dont work properly cause of normals, what values?
  Hey I''ve got a square made of 4 points using TriangleStrip.When I bring my point light right up to it, it doesn''t light up. But my meshes that are right next to the square light up as i have called ComputeNormals on them.So I believe the problem is with the values i assigned to my normals for the four vertices.heres what my normals are.   ac.vertices3D[0].normal  = D3DXVECTOR3(0,1,0);ac.vertices3D[1].normal  = D3DXVECTOR3(0,1,0);ac.vertices3D[2].normal  = D3DXVECTOR3(0,1,0);ac.vertices3D[3].normal  = D3DXVECTOR3(0,1,0);what do you suggest i set my normals as? What i want is just for the light to be reflected back, so if i got a point light right next to my square i can see it, if im looking at it from any angle facing it. 
  You''ve got your normals along the y-axis, I think what your looking for is (0,0,-1) for all vertices, that will (in a left handed system, which is what d3d uses) make your face "point" (for want of a better word) towards the negative z axis..   Dave.
