(I know - we are too big to enter - BUT we can see it).
Don't be to sure, there is another glitch I never found a use for that involves sub-worlds
Before you link the sub world dummy to the sub world shrink it down using the scale feature.
But what ever you do,
do not use any of the modifiers to change the dummy, just the scale button
The one time I did I used the twist modifier and I ended up with a stack dump error and had to reload Uru CC
If I remember correctly when you shrink the sub world dummy like this it also shrinks the physics of the AV
Except for the camera, its like something out of Alice in Wonderland and might make for some interesting fun house mirrors
shhhhhhhhh don't tell the programmer,
the game engine was not designed to do this and it is taking a chance so back up Uru CC before you try it just in case.
