Well, i've been making a few terrain objects in 3D World Studio, and exported them into .X files. What I want to be able to do is load up the terrain model in DBP (obviously possible using the LOAD OBJECT command), and then look down on the terrain, so I can see what it looks like in-game.

I tried using some simple things like the LOAD OBJECT command, and then positioning the camera, but it didn't work.

All help is appreciated, thanks.

What exactly do you mean by "it didn't work"? Did the model not load? Was it somehow not displayed properly? Did you not see it at all? Did the program fail to run altogether? What were these "simple things" you tried? Did you have camera movement so that you could look around in case the terrain was there but wasn't where you thought it was going to be? Was your camera range set appropriately? What was the cull state of the model?

In short, we need more info.

Good point, thanks. I'll post the exact code I used and screens in a second.

EDIT : Here's the code i'm using, here, what i'm trying to do is get the player to walk along the terrain.

Sync On : Hide Mouse
`----------------( Setup Matrix )------------------------------------------
PRINT "LOADING....."
LOAD OBJECT "MAP.x",1
LOAD IMAGE "CYGRASS1.bmp",1
POSITION OBJECT 1,0,0,0
TEXTURE OBJECT 1,1
MAKE OBJECT CUBE 10,5

`----------------( Main loop  )-------------------------------------------
Do

`Control input for camera
  If Upkey()=1 then Move object 10,1
  If Leftkey()=1 then Yrotate object 10,Wrapvalue(Object Angle Y(10)-5)
  If Rightkey()=1 then Yrotate object 10,Wrapvalue(Object Angle Y(10)+5)
  Yrotate Object 10,wrapvalue(Object Angle Y(10)+MouseMoveX())

`Slide Object On Matrix

_ChaseObject(10,10,15,1)  `Chase Object With 3rd Person Camera
`Display Frames Per-Second
  Set Cursor 1,1 : Print Screen FPS()
 Sync
Loop

Function _ChaseObject(ObjectNum,Dist,Hei,MatrixNum)
  `Store Object angle Y in aY#
       aY# = Object angle Y(10)
  `get player object position and store in X# and Z#
       X# = Object position x(ObjectNum)
       Z# = Object position z(ObjectNum)
       Y# = Object Position Y(ObjectNum)

`get new camera position and store in cZ# and cX#
       cZ# = Newzvalue(Z#,aY#-180,DIST)
       cX# = Newxvalue(X#,aY#-180,DIST)

`position camera
       Position Camera cX#,cY#,cZ#

`point the camera at the player object
       Point camera X#,y#+5,Z#
EndFunction

+ Code Snippet

you are to low on the terrain

add some value to the camera y# position like:

Position Camera cX#,cY#+200,cZ#

[edit]
also notice that you are not checking the terrain height at player position

this may do it:

Function _ChaseObject(ObjectNum,Dist,Hei,MatrixNum)
`Store Object angle Y in aY#
aY# = Object angle Y(10)
`get player object position and store in X# and Z#
X# = Object position x(ObjectNum)
Z# = Object position z(ObjectNum)
th#=intersect object(1,x#,10000,z#,x#,-10000,z#)
y#=10000-th#
position object 10,x#,y#,z#

`get new camera position and store in cZ# and cX#
cZ# = Newzvalue(Z#,aY#-180,DIST)
cX# = Newxvalue(X#,aY#-180,DIST)
cy#=y#+100
`position camera
Position Camera cX#,cY#,cZ#

`point the camera at the player object
Point camera X#,th#+5,Z#
EndFunction

I'm still getting the exact same result as before with the code you suggested Scorpyo, but thanks anyway.

Current code :

Sync On : Hide Mouse
`----------------( Setup Matrix )------------------------------------------
PRINT "LOADING....."
WAIT 10
LOAD OBJECT "MAP.x",1
LOAD IMAGE "CYGRASS1.bmp",1
POSITION OBJECT 1,0,0,0
TEXTURE OBJECT 1,1
MAKE OBJECT CUBE 10,5

`----------------( Main loop  )-------------------------------------------
Do

`Control input for camera
  If Upkey()=1 then Move object 10,1
  If Leftkey()=1 then Yrotate object 10,Wrapvalue(Object Angle Y(10)-5)
  If Rightkey()=1 then Yrotate object 10,Wrapvalue(Object Angle Y(10)+5)
  Yrotate Object 10,wrapvalue(Object Angle Y(10)+MouseMoveX())

`Slide Object On Matrix

`Chase Object With 3rd Person Camera
`Display Frames Per-Second
  Set Cursor 1,1 : Print Screen FPS()
 Sync
Loop

Function _ChaseObject(ObjectNum,Dist,Hei,MatrixNum)
`Store Object angle Y in aY#
aY# = Object angle Y(10)
`get player object position and store in X# and Z#
X# = Object position x(ObjectNum)
Z# = Object position z(ObjectNum)
th#=intersect object(1,x#,10000,z#,x#,-10000,z#)
y#=10000-th#
position object 10,x#,y#,z#

`get new camera position and store in cZ# and cX#
cZ# = Newzvalue(Z#,aY#-180,DIST)
cX# = Newxvalue(X#,aY#-180,DIST)
cy#=y#+100

I apologize, I realize now that i left many mistakes unchanged in your code
here's a working example
