exporting texturecoords

This pseudo-code does the trick:

textranspiv = CreatePivot()

t_offsetu#	= "The texture offset U"
t_offsetv#	= "The texture offset V"
t_scaleu#	= "The texture scale U"
t_scalev#	= "The texture scale V"
t_angle#	= "The texture rotation"

For vert = 0 To CountVertices(surf)-1
	ScaleEntity textranspiv,t_scaleu,1,t_scalev
	RotateEntity textranspiv,0,-t_angle,0
	TFormPoint VertexU(surf,vert),0,VertexV(surf,vert),0,textranspiv
	u# = TFormedX()-t_offsetu
	v# = TFormedZ()-t_offsetv
