Creation of multiple meshes and textures.

I did try that. Below is the code from an example that I use.
If you can see where I am "slipping up", then I will keep at it.
I get "entity does not exist", but if I rem out the "position entity" it accepts the load command.
I wonder if my b3d exporter is duff. Hm.
;......................................................................................................
; LoadMesh Example
; ----------------
Graphics3D 640,480
SetBuffer BackBuffer()
camera=CreateCamera()
light=CreateLight()
RotateEntity light,90,0,0
; Load mesh
house=LoadMesh("all.b3d")
PositionEntity house,0,0,MeshDepth(house)*2
While Not KeyDown( 1 )
RenderWorld
Flip
Wend
End

Thanks for your good advice.
