Thank you very much for your stadiums , their quality is simply outstanding!
For the exteriors, it is possible to extract the bcstadiumcams.dat file of one of the stadium you listed above with cgfile explorer. Make a copy of the extracted file. Edit with a hex editor the copied file and replace one of the STAD_ID from part of the file code shown bellow
Code:
€?STAD_1:STAD_2:STAD_5:STAD_6:STAD_137:STAD_246...Stadium Exterior 2
with the STAD_NEWID you want (ie: STAD_193)
Code:
€?STAD_1:STAD_2:STAD_5:STAD_6:STAD_137:STAD_193...Stadium Exterior 2
You have to do it for every block with STAD_IDS (6 times?).
Save the file , then put it inside the appropriate game folder (data/bcdata/camera) then regenerate with the tool of your choice and "tadam* you have the exterior view for any stadium you want.
