You need to not cull the object and
position the camera inside the sphere

use SET OBJECT 1,0,0,0,0

if you cull your objects witch is the default
you can`t see the inside of most objects

a db primitive is ok, just remember to

set object cull objnum,0 (in pro)

or

make object sphere 1,-200 (in classic or pro)


the first command allows you to see the back face of surfaces that face away from you, the second (negative object size) has the same effect (turns the object inside out...like a sock, you get the inside on the outside and vice-versa), you could also use the set object command but both of the above are less trouble.

ps: when you get to using collision don`t forget to set the object collision off for the sphere you have used for the sky, since you are inside it you are colliding with it all the time, if you leave it`s collision on then results will not be what you expected.
