can some one help me to extend the size of delphino plaza?

[robinpup]

it was thinking about expand the size of that stage, and add more collisons to it, the stage is huge, but the playable areas are small, can some one tell me how to do it step by step  :kdance:?

Adding collisions to the stage should be easy, so I guess you won't have any problems with that.
But what you need to do to expand the boundaries is to edit:
Camlimit0N (Camera boundaries)
Camlimit1N
Dead0N (Death boundaries)
Dead1N.
These are bones inside the "StagePosition" MDL0s in "ModelData[100]" - "ModelData[120]. There are 10 MDL0s.

To guide you which Models corresponds to which position:
      Start (main platform)
02  Shore 1 (pipe)
03  Main Area
04  Boat (water canal)
05  Rocks rising up of the water
06  Shore 2
07  Rooftop
08  Place with the two parasols
09  Shine Tower
10  Shine Plaza (small fountain)

There's also some models called "StagePosition_ashibaB", C and D
I think those are for the different platforms on the main platform.
