Hi Puki, Just made a slight update to the code which seems to work fine, here it is:

Graphics3D 640,480,16,2
SetBuffer BackBuffer()

cam = CreateCamera()
MoveEntity cam, 0,0,-12

light=CreateLight(2)
LightColor light,0,0,255
MoveEntity light,1000,1000,-1000

light2=CreateLight(2)
LightColor light2,255,0,0
MoveEntity light2,-1000,1000,-1000

mesh = CreateMesh()

surface=CreateSurface(mesh)

triangle1 = CreateSurface(mesh)
sv1 = AddVertex (surface,-2,-2,-2)
sv2 = AddVertex (surface, 0, 2, -2)
sv3 = AddVertex (surface, 2,-2,-2)
tv1 = AddVertex (triangle1,-2,-2,-2)
tv2 = AddVertex (triangle1, 0, 2, -2)
tv3 = AddVertex (triangle1, 2,-2,-2)
tri = AddTriangle (triangle1,tv1,tv2,tv3)
tri = AddTriangle (surface,sv3,sv2,sv1)

UpdateNormals mesh

While Not KeyHit(1)
TurnEntity mesh,0,1,0
RenderWorld
Flip
Wend
End

Has abit more coding but the results come out to be better.
