I've been trying my hand in 3D lately and I've only really come accross one major problem. I have a few models made, and I REALLY want them to look good so I made my own model viewer to show off to my friends what I can do. However, when I tried to apply the textures, I end up with something that looks terrible. Heres the code currently

; PaintMesh Example
; -----------------

Graphics3D 640,480,32,1
SetBuffer BackBuffer()
AntiAlias True
HidePointer()

camera=CreateCamera()

light=CreateLight()
RotateEntity light,90,0,0

mesh=LoadMesh("C:\Program Files\Blender\.blender\Stuff\Trojan Horse\trojan horse.3ds")
world = CreatePlane()
PositionEntity world,0,-5,0
PositionEntity mesh,0,0,10

; Load texture
tex=LoadTexture("C:\Program Files\Blender\.blender\Stuff\Trojan Horse\wood2.jpg")
TextureCoords(tex,0)
tex2=LoadTexture("MossyGround.BMP")
ScaleTexture(tex2,2,2)

; Create brush
brush=CreateBrush()
brush2=CreateBrush()

; Apply texture to brush
BrushTexture brush,tex

; Paint mesh with brush
PaintMesh mesh,brush
EntityTexture world,tex2

clouds=LoadTexture( "cloud_2.bmp",3 )
ScaleTexture clouds,1000,1000
p=CreatePlane()
EntityTexture p,clouds
EntityFX p,1
PositionEntity p,0,250,0

p=CopyEntity( p )
RotateEntity p,0,0,180

While Not KeyDown( 1 )
	UpdateNormals(mesh)
	lastmousex%=MouseX()
	lastmousey%=MouseY()
	yaw#=(320-MouseX()) + 360 Mod(360)
	pitch#=-(240-MouseY()) + 360 Mod(360)
	MoveMouse(320,240)
	TurnEntity camera,pitch,yaw,0
	x#=0
	y#=0
	z#=0
	If KeyDown( 208 )=True Then z=z-.25 
	If KeyDown( 200 )=True Then z=z+.25
	If KeyDown( 203 )=True Then x=x-.25
	If KeyDown( 205 )=True Then x=x+.25
	MoveEntity camera,x,y,z
	RenderWorld
	Flip
Wend

End

Obviously you're not going to be able to run that without the textures and meshes so heres a sample of what I'm talking about.

Those textures are SUPPOSED to be straight horizontal...

The way a texture is displayed is dependant on the Uv coords set up for each vertex of the model. Looks like this is your issue.

I see there ARE some UVs. Only they don't seem to be right. Maybe you should try an other UV coords set, try:

TextureCoords(tex,1)

I think that I have already tried texturecoords(tex,1) and there wasn't a great result... I'll give it another shot though. If that does not solve the problem, then does that mean that I am going to need to reset a setting for each and every vertex?

If the UVs are correct in the editor, they might have been exported wrong somehow. Maybe the export settings are wrong or the model needs to be collapsed before exporting ?
