Hi, all I am looking for a way to have a second 3D window within the main 3D window of my game. This is because I need to display a second camera top view to show a mini map Any help? EDIT: I forgot to mention that I want to have this window anywhere on the screen and not only to the upper left corner

You could maybe use CameraViewPort. The z-order is determined by the order the camera's are created.

CameraViewport command? http://www.blitzbasic.com/b3ddocs/command.php?name=CameraViewport&ref=3d_cat

Thanks guys, but with this simple method you can have a minimap ONLY to the UPPER LEFT corner. Is it possible for example to move the second view to the UPPER RIGHT corner? Probably I could render the output of this camera to a memory buffer and then place this buffer anywhere on the screen, but before try I wanted to know if this is a slow process...

For this, you can use the x/y parameter of the command: ; CameraViewport Example ; ---------------------- Graphics3D 640,480 SetBuffer BackBuffer() ; Create first camera cam1=CreateCamera() ; Set the first camera's viewport so that it fills the top half of the camera CameraViewport cam1,GraphicsWidth()/2,0,GraphicsWidth()/2,GraphicsHeight()/2 ; Create second camera cam2=CreateCamera() ; Set the second camera's viewport so that it fills the bottom half of the camera CameraViewport cam2,0,GraphicsHeight()/2,GraphicsWidth(),GraphicsHeight()/2 light=CreateLight() RotateEntity light,90,0,0 plane=CreatePlane() grass_tex=LoadTexture( "media/mossyground.bmp" ) EntityTexture plane,grass_tex PositionEntity plane,0,-1,0 While Not KeyDown( 1 ) If KeyDown( 205 )=True Then TurnEntity cam1,0,-1,0 If KeyDown( 203 )=True Then TurnEntity cam1,0,1,0 If KeyDown( 208 )=True Then MoveEntity cam1,0,0,-0.05 If KeyDown( 200 )=True Then MoveEntity cam1,0,0,0.05 RenderWorld Text 0,0,"Use cursor keys to move the first camera about the infinite plane" Flip Wend End

Oops! Thanks b32. My question was so stupid. I felt like an idiot when I checked you code...
