Textures on a mesh/surface/triangle?

Blitz3D Forums/Blitz3D Beginners Area/Textures on a mesh/surface/triangle?

Okay so far i can creat ea "cube" ,etc mesh and texture it, but using Addvertex, addsurface, add mesh whenever i try to paintmesh, entitytexture, paintsurface, it all appears as 1 color. The texture i'm using is black/red checkerboard? Im guessing its only painted one pixel of it?
heres my code...
Graphics3D 800,600,16,3
SetBuffer BackBuffer()
light=CreateLight()
RotateEntity light,90,0,0
world=CreateMesh()
surf=CreateSurface(world)

v1=AddVertex(surf,0,10,0)
v2=AddVertex(surf,10,10,0)
v3=AddVertex(surf,10,0,0)
tri=AddTriangle(surf,v1,v2,v3)
surf2=CreateSurface(world)
v4=AddVertex(surf2,0,0,0)
v5=AddVertex(surf2,0,10,0)
v6=AddVertex(surf2,10,0,0)
tri2=AddTriangle(surf2,v5,v6,v4)
cam = CreateCamera()
UpdateNormals world
PositionEntity cam,0,2,-15
brush=LoadTexture("c:\blitz\checker.bmp")
EntityTexture world,brush
RenderWorld
Flip

WaitKey()
