Just throwing this out there to see what you guys think...
It would be cool to be able to "jump to" other planets and use the interface buttons to edit and make another whole world, then be able to go between the two.
View one planet from the other, and vise versa.
(you can't do this now can you? My thought was you could have a "editing planet 1" or "now editing planet 2" and use all of the controls in the interface at the top to do so)
I know that this may be horrible as far as render times go, but perhaps since one planet would be far away it could be abstracted in some way to not have the full render weight?
Anyway, I'm not sure of the logistics, but I like the concept
I cannot thank Planetside enough for making Terragen2. This software is like a dream come true for me, being able to create these worlds is surreal!
