I did something psuedo-3d by having a new Z var (can be anything, just not "z"). I then edited move so that an icon can enter a dense obect if it is not in the same Z level. This gives some interesting effects, like tunnels that only short people can enter, etc. You could do things like that before, but this way you can see that they physical don't fit.

the best part is this would work from an above-down or first-person view. (though first isn't as good of course)

I hate 3drad. Get A5 if your looking for 3d worlds. My friend and I detailed half our neighborhood with every single house that you can walk in to. We scripted our own enemies in 20 mins and i made 3 fully animated models in their nice free modeler.

i know that a5 its self is not free, but i was not aware of the modeler. What file formats does it support, and do you have a link with more information about it(the modeler)?
