Any ideas on how to have a massive draw distance? I want the player to have a real sense of being in a really big, open space, and skyspheres always seem to hemm in and obscure distant objects. Are there any good work arounds to allow this?

Cheers

Well, you can change the clipping range, use fog to add a fine haze to distant objects, reduce the scale of objects to increase the appearance of available space, slow down the speed of players so it takes longer to get from point A to point B.

The default clipping range is 3,000 units. If you scale everything so that one unit is equal to one meter, that gives you a 6 kilometer vista from one horizon to the next.

One fog trick is to make the fog color and the horizon color the same, this will make a seamless transition from ground to sky. Of course, black fog can be used for night time scenes.

Thanks for the help zircher, but I intend to set this in space, and I want to be able to move to planets in the distance. I should really have mentioned this in the first place, sorry.

Ive considered playing with scale but I dont think I could make ships etc small enough.

Try scale object and set all parameters to 1. Then change the FOV to something really low like 0.1 or some really small number that works. The problem with a big draw distance is the z-fighting, which would look terrible. Maybe you could take a look at Freelancer and try to find out what they did there.
