view distance
 

when i have a really big scene (not in terms of polys but in terms of physical dimensions) the oblects in the distance dissapear
i think i need to change the draw distance but i dont know how

You can do this in the Camera Settings.

In your window panel.

View > Select Camera

Ctrl A

In the Attributes

Camera Attributes

Far Clip Plane.

It`s normally set to 1000.000 change it to as high as you need it too.

Have fun with the big scene :)

cheers
its for a school project
a spaceship crashes to the ground fro space so i need a big enviroment

I have a similar problem.

If I go to top or side view my character disappears. but in perspective is there. I opened my view to max an min. If I'm looking at top, and click side I see the charter move but then vanishes.

Have you changed the viewing distance?
